since u been in the hobby how much messing around have u done to get all ur tanks the way u want them? ill go first. i wont mention lenghts because there all big. but i have 1 silver arrow/2,dorados/1gar/1pbass/2bowfins/2clownknifes/1stingray/1africanpike/2:reddevils/2loisellis/1goldlineknife/1blackstripepike/3differentpikecichlids/1epo/1jardini/1fahaka puffer/1exodon/2hujetagars/1tigershovelnose. anyways that covers most of my fish but it took awile to see which ones would work out in each tank. I have also discovered a way to make fish not fight with each other. I should say i found a way that works for me.
