i bought one otto cat yesterday to accompany my other two otto cats in the tank because i heard they like to be groups. it went well and i saw the three of them happily chasing each other, eating together and staying on the same leaf. but when i got home today two otto cats were died. and i suspect they were my first two otto cats and not the one i just bought! what happen?? can someone tell me?

also i have two rams in my tank. is it them who are nipping my neon tetra's tail? what will stop them? must i move them out?

thanks for all the help!
 
First off, how big is your tank? It doesn't sound very big, because all those fish should happily live together. However, depending on the species of ram you have. You have to remember that they are cichlids and have the typical cichlid attitude when it comes down to it. I would say that most likely your rams killed the two ottos and having been trying to kill the neons, but can't catch them.
 
There are too many reasons for newly-acquired Otocinclus to die to hazard a guess from a distance. After a group have acclimated for a month, they'll be much hardier, IME.

Rams aren't generally fin nippers. Ragged fins are more usually a combination of minor ectoparasites followed by fungi and bacteria that take advantage of compromised fin edges, also IME.
 
i have a two feet tank. about 45 litres? my rams i'm not sure what type they are but according to the lfs they said that they can live in a community tank with no problems. one of them is orange the other is pale with black strips. my ammonia is 0, nitrite is 0, pH is 7. my tank has been running for perhaps 1-2 weeks. actually it is an establish tank of 5 months plus just that bubbles started coming out of the gravel. so redid the whole tank but the filter media was saved. my first 2 ottos managed to surivive through the whole transition but upon the addition of one new otto on monday, the next day they died! i have really no idea how this happened! i really loves my first 2 ottos.. =(
 
I've seen rams down right attack other fish to death so it's possible that happened. Ottos are basically a smaller version of a pleco so what a pleco is capable of, I would guess an otos is as well. Anyone have any thoughts? would an oto attack another?
it's possible the new oto went rogue =)
 
its a bolivian ram if i am not wrong. and i realize my 2 albino corys has also been nipped on the fins!! i have no idea what else to do either then feeding them excess so that they won't be hungry and nip my other fishes or buy another tank to put them in!

what would you suggest?

thanks!
 
Fin-nipping isn't related to hunger in any way.

And not all fin erosion is due to nipping by other fish. Often it is a secondary infection of bacteria and Saprolegnia after single-cell parasites have broken the tissue surface.

Are the barbels on the albino Cories "wearing down"?
