Indian yellow tail blue
Hello, Bob n
just wanted to bring to your attention, the variety of yellow
tail blue damsels available in India. Well the coloration is a
tad dark and the shape of the body and the yellow of the tail
The specimens I have seen, have a long body unlike the shorter
one of the commonly accepted yellow tail blues, almost
bullet/torpedo shaped and the yellow is restricted to the tail
<And the pectoral fins seem/appear light colored as well...
And the "eyelid" above and below the iris might be
which in the normal ones overlaps onto the body a slight
bit. I am attaching a few pics of
the specimen I had and that of the commonly accepted one. Please
do tell me if I am looking at a different variety or if it is
just a figment of my imagination. Sorry for the bad quality of
the pics as they were taken with a phone camera and are very old.
Thanks in advance and really good to mail you guys n gals after a
<In reviewing the pix here:
this looks like it might be Pomacentrus caeruleus, P. similis...
both are found in and about your region. Bob Fenner>
|Re: Indian yellow tail blue
Hi Bob, Thanks for the effort. I forgot
about the pectoral fins. And P. similis is perfectly matched to the
ones I have had. These are sold as the so called "yellow tail
blues here. Thanks again, Blesson.
Allen's damsels 4/12/12
Hello Wet Web Crew!
I have heard that Allen's Damsels are one of the least aggressive
of the damsels.
<A relative term in relation to Damsels. Pomacentrus genus--
There does not appear to be a whole lot of information out there on
them, and I seem to be finding much conflicting information as to
whether they could do well in a small group, say about 5, in a fair
size aquarium of 125 gallons.
<It's possible that the tank is large enough for each fish to
claim its own territory but do not expect them to peacefully coexist as
one large group.>
Your esteemed opinion will settle any conflict. Over time, am I
asking for a damsel bloodbath if I try for a small school of Alleni in

Perhaps you can assist me with that... Other than Chromis, what other
interesting or colorful schooling fish are there?
<Getting fish to school in captive systems, excluding very large
systems, can be a difficult task but there are options. There are
multitudes of Anthias to choose from which will form harems in captive

While not a school, a pair of Heniochus acuminatus can be quite
striking and rarely leave each others side. These should be introduced
at the same time and to a mature system. More here- http://www.wetwebmedia.com/heniochu.htm

Damsel Compatibility and Refugium for

damsel (Pomacentrus coelestis)
<A social species>
I'm going to be upgrading to 100 gallon. So far I have no problems
as I intended to keep my damsel as the lone fish in my 40 gallon,
however I wish to keep more fish in my 100 gallon, a harem of 10 Dispar

the above mentioned stocking list?
And can you please point me in the right direction to set up a refugium
for zooplankton without any form of macro
algae like a rubble zone refugium. Thank You for all your help.

Pomacentrus alleni ID 1/20/10
I am wondering what you would consider a "defining
characteristic" for P. alleni. My LFS 4 fish in that I believe are
P. alleni, but he has them labeled as something else. I want the P.
alleni because of their more docile nature and don't want to make
the mistake of introducing a different damsel into my tank. These fish
are neon blue with some yellow around the anal fin.
<Hence the name, Neon Damselfish.>
They DO have the black stripe on the bottom of the caudal fin. Does any
other damsel have this feature, or is this a good indicator that they
are in fact P. alleni?
<Without a pic, your description sounds like the Neon Damselfish,
and I do not understand why you are writing as this information is
easily found by Googling.
Take a look at the attached pic for comparison.>

Pomacentrus alleni Query
I put this query into the emails with image but it is not my image,
just sent to querior for reference. I know you do not use other peoples
work on your site for good reason so I just want to give you a heads up
<Real good. Thank you, B><<Mine's here: http://wetwebmedia.com/pomacentrus.htm>>
Pomacentrus auriventris Addition 2/11/07 Hey guys
<Hello.> -- First off, props for all you do for the hobby.
<Thanks.> Here's my stocking question: I've got a 45g
cube (24"x20"x22") (another 10g in a 15g sump), solid
skimmer (Reef Octopus NW-110). I've got around 50lbs of
rock -- even though it's porous, MI stuff, I still need to add a
few pieces for caves. I've got a 3" starry blenny
and a 2.5" maroon clown (blenny first, clown 4 weeks later -- been
in together for about 13 weeks). I'm strongly
considering adding a trio of Pomacentrus auriventris to the tank, as my
final inhabitants, fish-wise. Thoughts on this? <In this
size tank could work...may quarrel with he maroon as he/she ages
though...is a risk but I would say with this species odds are in your
favor.> Alternatively, I add one of the tougher
Dottybacks, but I'd rather have a fish that's out in the open
all the time (the blenny is awesome, but hides a
lot). Thanks for your advice! <Anytime.> ~Tim <Adam
Sexing Pomacentrus coelestis I have searched high and low on
the net. How can I differentiate male from female of this sp. ?
Any and help is more than appreciated. Thank you for

11/01/05 Hey Bob or Steve whoever gets this. <Ali here...> I
have a 75 reef and for a while there was only a damsel in the tank (my
parents took care of the tank this summer for me and that's all
that was left) I just recently added a flameback to the tank and the
damsel is going crazy. He is attacking it and showing a lot of
aggression. <Typical behavior for a damsel who has had a tank all to
himself for a year.> I have the lights turned off now and there is
over 100 pounds of rock in the tank. I don't know what else to do
if this doesn't stop I think the pygmy will die. I can't trap
out the damsel there is too much rock. Would adding another fish calm
the damsel down so its just not the two of them? thanks any help will
be great. Matt <Matt, you are in a dilemma here. More than likely,
the damsel will not stop showing constant aggression towards the angel.
Both fish more than likely have very similar body shape/size and diet.
A damsel that has 'owned' and dominated the aquarium all by
himself can be especially terrorizing towards other small fish.
Generally speaking, the flameback pygmy angels are an assertive fish
that can hold their own with many other species of fish. However a
newly added, un-QT'd fish placed within the grasps of a
well-established, dominant damsel isn't really the best practice.
Please consider removing some rockwork and gently trying to trap or
catch either fish. I would not add anymore fish in the aquarium as the
next fish you add will most likely suffer the same unnecessary fate as
the angel. Good luck. - Ali>
Damsel Caught! 11/04/05 (Wha.. huh? It's only the 3rd!)
11/3/05 Thanks for the quick reply Ali I did forget to mention the
flameback was held in a QT tank for 2 weeks before I put him in the
display tank. I took almost all of the rock and coral out of the tank
and captured the damsel and put him in the back sump of the tank (Sea
Clear System II). <You are the man Matt! Great to see you taking
action and taking your angel out of harms way. Kudos my friend.> I
feel quite bad the fish is being held back there, in your opinion how
soon can I release the damsel back into the display tank? It is a
Princess damsel (Pomacentrus vaiuli) which I have personally never seen
for sale here on the east coast. It was a gift from a friend I met at
Marine Ornamental's 04 in Honolulu so I really want to keep this
fish but I trust your opinion if you feel he will just cause problems
if he is put back into the display. <He'll be okay in the back
of the System II sump for several days, but do make it a point to find
him a good home as soon as possible. These particular damsels do not
need a huge amount of room therefore, one option you can consider is
setting up a 15 gallon aquarium/refugium plumbed into your existing
system to house the damsel along with some live sand, plants, and
clusters of live rock. This way you can enjoy your fish while
simultaneously reaping the benefits of a refugium. If this is not an
option, setting up a small 10 or 15 gallon kitchen tank, with some live
rock, sand and hang-on power filter will work just fine for this little
guy. Otherwise, start placing ads at your local marine club or internet
fish forums stating you are seeking a good home for the fish.> By
the way pictures of my 1500 reef are on the way. Thanks again you guys
take care. <Looking forward to them Matt. Good luck! - Ali>
Re: Australian damsel G'Day Crew, I live on the central
east coast of Australia. I have a license for private aquarium
collecting. Yesterday I captured an Australian Damsel (Pomacentrus
australis). I have identified the fish using an excellent book, Coastal
Fishes Of South Eastern Australia by Rudie h. Kuiter. <Rudie has
many good books out. A few more re Australian fishes> I have been
searching to find more info about this fish, e.g. behaviour, feeding .
This may be a long-shot but i thought I'd try you guys. Have you
heard of this fish &/or got any info on it? <No... all we have
on the genus is here: http://www.wetwebmedia.com/pomacentrus.htm
You might try fishbase.org> Also do you know any good Australian
internet sites like yours? Thanks Stephen.

|Stocking list + damsel id Hi. As always
Muchos gracias for all of the help. You (collectively) continue to
amaze me... I'm sure this is a chore at times, but what
satisfaction you must get. <You are so right> The fact that
most of your responses not only help the person who asked, but so
many others, and then over and over again as people read the site.
Super cool. <By design... thank goodness for the Net!> Two
questions. 1. I need some help with a damsel id. I've attached
two pics. It was sold as a "Scott's Damsel" by a very
good store, who can't figure out the scientific name ;-)
I've only found one reference to that name anywhere, from a
site for an Indonesian collector which lists it as Chrysiptera
medanensis. I'm guessing some kind of Chrysiptera or
Pomacentrus (maybe caeruleus, but I don't think so). I have
three and they are the most submissive in the tank. <It is P.
caeruleus almost assuredly. Please see here:
http://www.wetwebmedia.com/pomacentrus.htm or source it on
fishbase.org> 2. I currently have the following fish in a 110g
60x24x18 tank with 150lbs LR and a 30g sump. Tank houses SPS,
clams, typical assortment of small inverts. (1) Kole tang
(Ctenochaetus strigosus) (1) Hippo tang (Paracanthurus hepatus) (4)
Orange lyretail Anthias (Pseudanthias squamipinnis) (3) Scott's
damsel? (1) Diadem Dottyback (Pseudochromis diadema) This is about
as full as I would like, but am considering two final additions,
and would like your advice. All of the current tankmates are
getting along well. None have acted aggressively toward others. All
of the Anthias are female, and I would like to add a male. The
females have lived here for a month. Nobody seems to have selected
herself as the leader. Would the introduction of a male at this
point be recommended? <Should not be trouble...> I would also
like to add one six-line wrasse to help the clams. I am concerned
that the wrasse and the Dottyback might not get along. <Might
not... but given sufficient rock cover... I give you good odds>
The LR is organized such that there are many hiding places and lots
of swimming space. The Dottyback pretty much just guards it spot
with an occasional foray into the other end of the tank, but
doesn't bother anyone. You advice is appreciated (more than
you'll ever know). Regards, Michael
<Be chatting, Bob Fenner>
Help identify a damsel I was wondering if you could
help id this damsel for me.......it was sold to me as a lemon
damsel.......it looks a lot like a lemon damsel except it has a
small black spot on its dorsal fin......and sort of resembles a
sulphur damsel...Thanx for any help <Yowsa, that's a small
(3k) image... this does look like either of the stated
Pomacentrus spp. Please go to the WetWebMedia.Com homepage and
put in the term Lemon Damsel... go to the genus Pomacentrus page,
and try to compare the juvenile you have with the images there.
|Re: help identify a damsel it looks a lot
like a "honey Chromis" Pomacentrus melas it doesn't
really matter what species it is I was just curious <Real, good.
Schooling fish? Mr. Fenner: I have a 180 gallon reef tank
with room for several more 2 inch fish. Ever since seeing a large
freshwater tank with a school of Neon Tetras, I have wanted to do
something similar in my tank. <Many possibilities> Unfortunately
the only schooling fish that I can ever find are the Blue and Green
Chromis. Both fish are too plain for my taste. I keep looking for a
more colorful schooling fish. <Perhaps the Anthiinae... oh, I see
you mention them below> Occasionally a LFS will recommend one of the
Anthias for schooling fish. Unfortunately they get big enough that I
don't feel my tank can support a school of 5 (in addition to what I
already have). <Read over our site: www.WetWebMedia.com re this
subfamily of basses... many choices....> I recently saw some
Pomacentrus alleni at my local LFS. The proprietor said that they were
the same "family" as Chromis, and would _probably_ exhibit
schooling behavior (and would _probably_ be relatively peaceful).
<Mmm, not really... Chromis are more a more likely general schooling
group (the species you mention)... not Allen's Pomacentrus...>
Can you give me some insight into the behavior of Pomacentrus alleni?
<See the genus coverage on the WWM site> Do you have other
recommendations for small, brightly colored schooling fish? <Many...
but this is not the way you should pick/choose amongst...> Thank you
for your time. Ken Matson
