who is the bully

[softak]

I have 3ft tank with:

2 L104(Male and female 2 years old),
2 suppose to be L66 from this thread: http://www.plecofanatics.com/forum/show ... hp?t=70648 (1+ year old)
2 Rainbow Bosemani (male+ female 1+ year old)
several cardinal tetras and approx 20 corydoras.
several endlers guppy

Today I found male L66 covered with blood and for last month I've lost 3 pictus catfish (all of them had blood and wounds ) and some other fish.
Question: who is the bully? male L104?

PS: Looks like, L104 had some eggs a week ago, but I can not find any alive fry in the tank.

I don't know what's going on in your tank, but I suspect L104

Panaque maccus

is not the culprit. I'm not sure who is - perhaps L066, but I would expect a Pimelodus pictus o get away from any Loricariidae.

Sorry to hear that you lost the eggs from your P. maccus - I have also had eggs but no fry.

I would actually be looking at the rainbows, some of them can be brutal on other fish.

Of the fish you mention none are known bullies. Mats is right that pictus should escape from threats (apart from some cichlids maybe). I can only agree that there may be some aggression between the plecs but that doesn't explain the pictus

Have you a photo? There is a vague possibility it is some sort of bacterial infection

Rainbows can be a funny fish with certain others but are not equipped to do damage to armoured cats
