FAQs on the Zebra Danios Compatibility

Question: my Danio's tail is gone
Hello!  I'm hoping you can help me.  I noticed yesterday that one of my Danio's tail was mostly gone (long finned Danio).  I have zebra Danios and plain Danios in my tank.  I thought they were a non-aggressive fish so I didn't think that anyone else would've bitten his tail.
His spine doesn't look bent.  He spends more time hiding in the foliage than he used to and seems a bit sensitive, but swims around with everyone some and eats fine.
Any ideas what is going on?  The tail nubbin' looks healthy as far as I can tell.
< If the tail was not actually bitten off by a fellow tankmate then chances are that it was damaged and may have developed a bacterial infection that slowly ate it away. Do a 30 % water change, clean the filter and treat with Furanace to prevent any further damage.-Chuck>
Thank you so much!

Re: Question: my Danio's tail is gone
Thank you for the info. Can the Danio grow a new tail fin?
< If the damage is limited to the fin portion itself then it may grow back. If the damage has reached the caudal peduncle, The meaty portion of the tail then probably not.-Chuck>

Pandas and Barbs Incompatible?
Hi!
I have a 10 gallon tank with 2 striped barbs and 2 long-finned Danios. All 4 fish are about 1" in size. Tank has been cycled and water tested. They have been living together for a few months now and get along great. I do a 20-30% water change every week. The other day I added 2 small panda Corys. Right away, one striped barb started chasing one of the Corys. This went on for a few days. Every time the panda tried to rest, the barb would seek him out and chase him. It only happened with one barb and one panda. Also, the barbs were hogging all the food, so we tried a sinking pellet for the pandas, but the barbs found that too and devoured it! Needless to say, when I got home from work one night, both pandas were dead.
I took them out and did a water change and the 4 original fish are back to normal. Will this happen with any new fish I add or was there some incompatibility with the panda and the barb? I feel like the barb harassed the pandas to death!!
< Some fish do get territorial and some barbs have been known to become fin nippers. Next time do a water change and rearrange the tank just before adding any new fish. This may help. Or you could try to add numerous fish at the same time to help disperse the aggression of the barbs.-Chuck>
Thanks,

Danio
We recently set up a 48 gal tank and we purchased 4 Long Fin Zebra Danios.
One of the Danios is chasing the other three and actually taking pieces out of the other tails. The pH is 7.6 and all other readings are in spec. The aggressive Danio is not bothering the other fish in the tank. It seems the other 3 non-aggressive Danios are not bothering each other, it is just the one that is aggressive.
Should we isolate the aggressive fish? Any help would be greatly appreciated. Love you website.
< You could either add more Danios or take out the aggressive one. I am afraid that if you remove the aggressive one then another one may become dominant and chase the others as well. A 48 gallon tank should be big enough so that they should have room to get away. I usually recommend that schooling fishes like these be kept in groups of at least 6.-Chuck>
