Do/will tropheus eat their fry? I have one that’s not opening its mouth like the others during feeding or while swimming. Smaller than the two dominant males and not as vibrantly colored with a gray face instead of all black.
I am not being successful with the tropheus. I have divided the tank to try to crowd them but I found this one yesterday. It is now on the opposite side of the divider so that it can heal.
I'm not in a position to increase numbers so I need to figure out what to do.
The dominant male tries to get at the injured male through the separator. I've considered moving the dominant one to the isolation side but am worried that would creat even more havoc within the colony.
I added a second divider to isolate the dominant male.
I have a 60g cube (24³) or a 29g I could move the colony into. The 29g would be easiest as it's already uninhabited. I just need to remove plants. The cube would require moving some corys and the arowana and plants which would not be a little more involved.
I have a 55g too but I think they would have to much room with that foot print.
Any recommendations from the experienced keepers would be helpful.
I would remove the injured fish and the dividers and see what happens next. Sometimes you get lucky and only lose a fish or two before the group becomes somewhat stable again. Crowding only works up to a certain group size. Using ever-smaller tanks doesn't help if individuals can't hide in the group. This only takes away the space for them to escape if they become a target.
But that is just what I would do. At this point everything is some kind of gamble.
I know people who went down to 3 or 4 fish and somehow managed to regrow a full group of 30+ from there.
So, because I am down to eight having lost my one juvenile to the bullies. I have let the one seriously injured fish convalesce and it is healing up nicely. The wound never festered or fuzzed and he never lost appetite either. Skin is growing over the injured site. Two more weeks maybe and I will try reintroducing him to the colony.
I have also added more rock and PVC pipe hides and left the lights off.
