So I'm not sure if these guys are mating or fighting, please help, it's getting real bad. My lutino has turned on all the other fish in the tank as well!!!
 
They will be moving soon, but right now they are in a 110, and they are only 10months old. Just want to know if they are fighting for not
 
they need bigger foot print, the blond looking for nest area territory. the tiger has no where to go.
 
What are the other fish in the tank? Yeah, a four foot foot print is going to cause issues with the adult sized Os as discussed in another thread today. What will the new tank be?

Ok, i understand they need a bigger tank, but I'm about to move next month and my tank is in the process of being built, custom 300gall, and up until yesterday 90% of the time the tiger was the aggressor, now they are facing off, this all started this morning after I moved around there tank last night, is this a breeding behavior or a male rivalry??? I can separate them If I need to. When they are not fighting they are with each other hanging out in their tube.
 
2 pictus cats and a rhino pleco. Everyone was fine until I rearranged the tank and removed a cpl plants and a piece of driftwood
 
I would make a divider out of lighting diffuser to keep them from bashing each other too much until you can move them

It could be breeding aggression, or plain old aggression, either way it can turn ugly. I've had plenty of established pairs go sour, sometimes the male goes as far as killing the female if he wants to mate and she isn't ready

Ok, thank you everyone for all your help. I'm moving my tiger to a 55 for the time being and well see what happens, that's all I can do right now, and for the best, this is a very very difficult thing to watch, i spend many hrs a day with my fish, and they have always been best buds, doing everything together, so to see them fall out like this is really rough!!! Thanks again everyone. All of you are awesome and much appreciated!!!!
