I will keep this short, I recently build a large vivarium/paludarium for my lizard (Caiman Lizard); the water component is ~130 gallons, and fish are safe for the lizard and vice versa (lizard eats snails);
Now, the lizard leaves the fish alone and the fish dont mess with the lizard; on advice (I know little about fish) I populated the tank with some convicts and 2 other s. american ciclids (I forgot their name, but was TOLD that they would be ok with the convicts. Now, all the convicts started around the same size, but two grew massive and had offspring (now I have ~24 additional 1/4" convicts running around);
The two larger convicts are terrorizing my other convicts and the other two fish (and have recently done some real damage, including eating off the caudal fin of one)
I am going to make another tank, but wont be ready for a while and dont have a place to move the larger fish right now.
Questions:
Should I euthanize the fish with the caudal fin damage (picture below)
WIll the other two cichlids eventually get big enough to fend for themselves, or should I look at rehoming them?
I feel bad for getting into this without knowing more, and THOUGHT I did my research, but apparently i did not.
I hate the idea of a bunch of fish being stressed/miserable, and am trying to find the best way to address this (perhaps rehoming the larger convicts)?
Thank you for any advice!
