And as far as the moving fish part - I feel like I run a day care of dysfunctional toothy fish. I'm adding, moving , changing up décor adding dithers, adding peacekeepers and constantly shuffling all the time. It's not usually that bad but sometimes it sucks. Had to rip all the driftwood out of that 300 to remove the catfish. Catching anything in the 750 is a nightmare and usually a 2 man job.
I bet fishing those Tor out of a 8x3 to add to the 300 will be a nightmare, the worst part is usually what the fish you're not trying to catch end up doing to themselves. I'll go to catch those Tor and will have 3 big ATF smashing into everything. The worst will be if I end up moving the Armatus out of the big tank and turning the ATF loose in there. Stupid Armatus are shanking fish I can't afford to replace.
But yes, definitely always interesting. Many times the stereotype doesn't match the fish - Gold Wolves and Aimara are perfect examples. 2 Aimara here doing fine in community settings and a Gold Wolf I can't house with anything.
