Cherry Barbs and Fin Nipping

[vequalsir]

some fish can just be nippers. Sometimes this is caused by something lacking in their diet.

What's your feeding schedule? What are you feeding them?

I feed them once a day...they are feed a variety of foods that include TetraColor Tropical Flakes, Shrimp pellets, HBH Super Soft Krill, and HBH Super Soft Spirulina.

That is quite a collection of species in one tank. A large planted aquarium?

Gold and cherry barbs are both known for being extremely docile. Rosies too fwiw.

Danios are mildly aggressive fish. Usually if you have enough of them they keep to themselves but yeah, whichever one is the alpha will tend to cruise the tank looking to enforce his dominance. I don't really care for their behavior with peaceful fish.

Also the Mollies, I've seen the males be prone to chasing fish.

Nutrition seems fine. I'd try sitting about 10 feet away, staying very still and watching the tank behavior. It should become obvious.

How many of each? A large enough school will keep any fin nipping within the group. If the school is too small the danios may be searching for other targets.

I agree with Zebulon, mollies and sometimes swordtails will nip on occasion. I would keep an eye on them as well.

 

[JL15219]

all the schooling fish are at least 10 or more

What can I do to help grow their tails back?

 

[Zebulon]

A couple days of Melafix might help the recovery time a bit.

Clean water is the best cure.

So doing a water change twice a week instead of once a week like I usually do?
