Fish dying..

[Jcs401]

Ok so I have a 24g nano and had 2 clowns 2 firefish, a meandering golby, and wrasse. I bought a copper banded shrimp and I saw it nip at a clown. Next morning woke up and it was dead. Few weeks later the other clown dead. I am now down to only two fish as my fiancé said "the mean shrimp I think killed the mandarin". I asked the store and they said the shrimp is peaceful and would never kill fish. Is this true because I have seen it nip at all of my fish?? PLEASE HELP!

Mandarins are extremely difficult to keep alive unless they are trained to eat frozen foods. Otherwise they need pods and LOTS of them. My guess would be that it starved to death. How long did you have it and what did it eat?

Shrimp typically don't attack fish. Some will try to clean fish, so maybe that was what was going on?

More info would really help...how long have you had the tank? What are your water parameters? When did you add these fish and how long did they live? Did any show signs of problems prior to dying? How do you acclimate them?

Also, what kind of wrasse did you have? Most smaller wrasses (fairy wrasses) need 50-90g, there are only a couple that I can think of that would be okay in a 24g (possum wrasses). Even 6 Line wrasses are best in a 30g+.

Was it a coral banded shrimp? If so, I can tell you that they can indeed be aggresive. I had one and one day I just happened to look at my tank and saw my 4 inch green coris wrasse struggling. Upon closer inspection the banded shrimp had the wrasse by the tail and he was struggling to get away. I quickly broke it up and the shrimp went back to the store.

Yes that's what I meant and I swear it took out three of my fish. He has now gone back to the store as well.

I had two coral banded shrimp that were aggressive.
