Attachment 21346Attachment 21347Attachment 21348Attachment 21345
This is 500L tank with 80+L sump.
Been thinking of selling the smaller ones, but when I think of the fact that I had them since 1" juvies and cared for them like babies, I just can't :( . After short period, they reaching 4" now and I'm starting to worries.
Plus, I have another 7" on his way ....; may be it is time to let some of them go or get another tank (the Mrs against it in an epic way " me or your fish", hope i could say "the fish" lol )
There are 3 breeding pairs in there and constantly competing over spawning location.

I feed them every possible food from BH to earthworms, blackworms and blood worms. They do not refuse any and I do weekly 40% wc and sump maintenance once fortnightly.

Please let me know if I'm overstocked my tank.

Yes i think you are but you feel the full impact of it when the fish get bigger and there will be world war 3 in the tank ,make sure you have a glass lid , you might get a jumper soon .
Nice fish by the way.
