I was kinda thinking the same thing. Every fish i own has a permanent home even if things dont work out in a particular tank. And even then, id just buy another tank to house them. That tank is grossly overcrowded purely from a biological standpoint. Its no wonder there are less fish at the end of the thread. Overcrowding is one thing, but that tank goes a bit past that. just my 2c of course. Like I said, I have 6 cichlids in a 300 and I feel I am at the limits of what might work longterm. And that's a big might..........
I have a 180 with a jag, midas, rtm, rt, and 3 juvenile barred midas..
The barred midas are being moved soon, and so is the rtm.
I have bichirs, and I still think it's crowded.
That RD and Umbee will kill off half of those fish. That expensive RT will go quickly, I would sell that fast.
