Re: New tank, Pangasius hypophthalmus, minnow shark, goldfish... stkg., reading  12/10/08
Hello dear Neale,
Thank you so much for your quick response, Neale I am interested to keep a small pair of blue line shark,
<Pangasius hypophthalmus? A bad choice. Too big for home aquaria, needs to be kept in groups of 6+ specimens.>
albino shark, one red tail shark
<Are we talking about albino Epalzeorhynchos frenatum and regular Epalzeorhynchos bicolor? They'll fight with each other. Best kept one specimen of whichever species, or in groups of 6+ specimens.>
and one pair of Bala shark
<Another big, schooling species. Six or more specimens, please.>
with my red cap goldfish.
<Nope; Goldfish should be kept on their own, especially "fancy" goldfish.
Too easily damaged by other, bullying fish species.>
Is this fine and under stocked? Neale how should I make my routine to change the water and what amount should I change and after how many days?
<Much written on WWM on this topic. Would recommend 25% every week as a good starting point.>
Please recommend me live plants so my aquarium looks more attractive and nice.
<Goldfish will eat soft plants, but robust types such as Vallisneria, Crinum, Java fern, Echinodorus, Cryptocoryne ciliata etc should be fine.>
Those plants which are not eaten by goldfish and sharks because when they eat they make huge mass.
Thank you,
Ali
<Cheers, Neale.>

Re: New tank... minnow sharks, goldfish comp. -12/11/08
Hello dear Neale,
Thank you so much for your time and help. Neale I am very much interested to keep sharks is there any kind which you can recommend me for my aquarium, or any other fresh water fish which is easy to keep and nice.
Actually to keep goldfish is very hard job and they make huge mess. They are also very sensitive like fin rot and other diseases. As they take long time to cure the fin rot even after 3-4 months my one red cap is showing the sign of fin rot, I do not how it would end completely. I am very much upset. Although its fine, healthy and active but when I see fin rot sign I become upset. I think shark will be easy to keep as they do not mass a lot, I really do not please help me if you can. Ill be thankful to you.
Thank You
Ali
<Hello Ali,
Goldfish are indeed difficult fish to keep well. That is why I explain to people they need big tanks and good filters. Goldfish are excellent pets, and can be intelligent and friendly. But they are much easier when kept as pond fish. I wouldn't recommend keeping any "minnow sharks" (as we call these fish) with Goldfish. Do read over Bob's article on minnow sharks. Some species get big, some are aggressive, and all need good water quality.
Until you can consistently ensure perfect water conditions with your Goldfish, then minnow sharks aren't an option. In other words, if you keep seeing Finrot and fungus, your tank isn't 100% perfect. Concentrate on this problem first! When you're happy the water quality is good, I'd recommend looking at other fish species that can live well alongside Goldfish, things like Plecostomus-type catfish and some of the gouramis. Cool water Corydoras such as Corydoras paleatus also work well. Cheers, Neale.>

Re: New tank   12/15/08
Hello Dear Neale,
Thank you so much Neale for time and help. God bless you, I will try to take care of my goldfish more so I could get rid of Finrot. Now they would have a lot of water and space. I hope they will enjoy more.
Thank You
Ali
<Ali, thanks for your kind words, and I am glad to be able to help. Good luck to you and your fish! Once you've settled things down and all the fish are healthy, we can talk some more about companion species. Cheers, Neale.>

FW Minnow Sharks, Pangasiid Catfish Shark... comp. mostly  6/5/06
Crew:
<<Paula. Tom with you.>>
I was reading your information on the different types of sharks/minnows. Under the Apollo shark it said "best kept singly." Does this mean only this fish in a small tank or only one of this type of fish along with others in a tank?
<<These fish don't get along with others of their species or with similar types of fish. Not an uncommon situation with certain varieties.>>
Also, will tri-color, iridescent, and Apollo sharks get along without fighting in one tank that holds about 40-50 gallons?
<<The Tri-color (Bala) Shark will quickly outgrow this tank. It's active and fast requiring lots of swimming room. Scratch the Iridescent Shark from your list completely. It can reach over three feet in length and shouldn't be sold to hobbyists. The Apollo Shark will probably see the Tri-color Shark as an adversary due to the similarities in their appearances. A 50-gallon tank would probably suffice for the Apollo Shark, however.>>
Thanks for the help.
Paula
<<Please continue your research, Paula. I commend you for doing your homework but there's still much to learn. My best. Tom>>

FW Sharks
Thanks for your quick response. When adding fish to a tank this size (90-gal.), what would you consider "slowly."
<One...then wait two weeks. Test the water. Add another etc>
I want to get a group of Bala Sharks and some compatible fish to make a community.
<No such thing as a shark with compatible fish. Please don't try this>
I know Balas get quite large eventually. How many should I add right away?
<I refuse to recommend/suggest that you buy any Bala sharks or any other species of sharks for that matter. It's a sucker purchase and the likely-hood that it will live long enough to grow large is slim to none. Why don't you "kill two birds with one stone?" 1) Save a fish's life by not buying any sharks and; 2) if you and others don't buy them, stores won't stock them. Now we're saving thousands/tens-of-thousands of sharks! I know they are cool to look at but they don't live.>
How big a group is logical to add in the near future? --Thanks,
<None, zero, zilch, nada. In Vegas there is a "Shark Reef" that has 6'+ sharks swimming around. Go check it out! Or go to Myrtle Beach South Carolina and check out the shark exhibit at the Ripley's aquarium. They have 12'+ sharks! Leave these creatures in the ocean or public aquariums. I apologize for being so blunt and repetitive but the truth isn't always pretty not is it necessarily what people want to hear. But it is the truth...none-the-less. David Dowless>
Charlie

Oops.. I made a blunder
I hope you had a good trip Bob. How was Belize?
<Unfortunately we didn't go... Our friend/roomie/travel partner Pete was too sick. So Di and I and he traded in our tickets to go to Kona next month. A good cancellation as I was able to get a bunch done here>
I wanted to tell you that I screwed up royally on a question last night. A guy wrote in and asked about stocking his tank with Bala sharks. Thinking that he was speaking of a saltwater species (that I hadn't heard of), I responded with the typical answer, "Don't buy any sharks!"...and like a fool...I rambled out my reasons. So now he's written back and I have apologized profusely and I'm feeling really stupid. I hate it when something like this slips through.
<No worries David. These happen. Apologize to the querier and go on>
I was also wondering...the response went out this morning and I would love for it not to appear within the website. I gave bad information and anyone that's in-the-know will recognize the information was incorrect. It's depressing enough that it will be on the daily facts but I really don't want to take the chance that this response would damage WWM's credibility by being permanently placed on the site.
<Not to worry re our credibility. We're human... will place a further comment from you right after>
I guess if I had finished the bio that you asked for you would know that I'm not very familiar with freshwater anything. I normally pass on these types of questions. I will finish the bio soon. Thanks for understanding that sometimes everything that can go wrong does go wrong. In the future, I'll be even MORE careful before responding to questions.
<Ahh, please do send your bio. along, with the areas you feel most comfortable with. If there is/are difficulties in queries, feel free to move them back to the in-box, or into someone elses folder>
Also...remember the New Wave CD Rom (Goemans) that you wanted me to review? I sent the review in and Susan wrote that a review had been completed by Moe and printed in October 2002! 
<What?>
Would you like to have my review for WWM's literature section?
<Yes, will post tomorrow>
I'll also tell you that Goemans and I had several enlightening and engaging discourses about this book. He seems like a great guy: very friendly, knowledgeable, loves the saltwater hobby, and willing to accept constructive criticism. He is also very impressed with WWM. I think I saved his final email. I send you a copy.
David
<Yes, have it. Bob.G is indeed a gentleman... and an actual scholar. Bob Fenner>

Bala Sharks
<Craig...would you please help this gentleman out? Thanks. David Dowless>
<Absolutely!>
90 gallon tank: I want to get a group of Bala Sharks and some compatible fish to make a community. I know Balas get quite large eventually. How many should I add right away? How big a group is logical to add in the near future? --Thanks, Charlie
<Hi Charlie, These fish can reach 14" in length and can be "aggressive".  Compared to the other minnow sharks they are relatively peaceful, but still will chase/nip on occasion so stick with fish of a similar temperament that can stand up under the pressure or that live out of the water column and are also tougher fish. The group of Balas will make any other choices more important. In a 90 you could probably accommodate 3-5 Balas (they are shoaling type fish) and perhaps a Pleco (watch size here, some can become quite large) perhaps a few Clown Loaches. Some of the larger Barbs would likely do alright as well, they are feisty and fast.  It is best to avoid overcrowding (start slow) and introduce the aggressive fish last, concurrently if small, and change decorations/set-up to throw territories off during intros.  Make sure your tank is well covered, Balas are notorious jumpers.  Best of luck, Craig>     

Black Shark
Could I maintain a Black Shark, (Labeo chrysophekadion) in a 48"x18"x20" tank, if it was the only inhabitant?  I love this species dearly, and I know
that they can get up to around 2', but my LFS buys them from a certain retailer, and they have kept these sharks before, and NEVER had one grow
past 16 inches.  So could I do it?  Thanks in advance for any answers!
<Could likely go in this size/shape system for a good long while. Other than size considerations, do keep an eye on this fish for its tendency to "get mean" with size. Bob Fenner>

Re: Black Shark
Hey Bob (or Anthony, or whomever may read this)!
I was told by Bob Fenner (if this is you, than you already know) that I could maintain a Black Shark (Labeo Chrysophekadion) in a 48”x18”x20” tank
for “a good long while”.  Is it possible for me to maintain this fish in there for its entire life?
<Mmm, yes, but it will be a greatly foreshortened life if so. Have seen this fish at close to two feet in length>
If not, how big of a tank would I eventually need.  I wasn’t planning on upgrading in the future, but if I must, then I
will.  Thanks in advance for any answers!
<Take a look at the stat.s on this species on Fishbase.org
Bob Fenner>

FW Tank Stocking
Can you please tell me what kind of shark can I put in my 10 gallon aquarium with my Cory catfish?  thanks!!
<Unfortunately there are no sharks, or shark-like fish that will live in a 10gallon, most of the freshwater fish with shark in their name, Bala Shark, Silver Shark, Iridescent Shark, all grow way to big for a 10gallon.  I would stick with a good looking school of Tetras; Neons, Cardinals, Black Neons, Emperors, Lemons, Rummy Nose, Glowlights... the list goes on and on and on and on (seriously) those are just a few of my favs.  Search fishbase.org for tetra, you'll see.  Best of luck, an no overstocking. -Gage>

Where to buy a freshwater shark - 1/17/05
Hi, where can I buy a baby freshwater shark? <Brian, not really sure if you are aware of what you are asking but I think you may be asking about the freshwater minnow "sharks" that are not really sharks at all. In any event, we don't sell anything at this site but any of our online etailers and or local fish store (pet fish store in your area) should be able to assist you. If you are looking for a freshwater shark that looks similar in appearance to a saltwater shark well.....there just isn't anything available but I think you are interested in these:
