Which of my fish would be best to put into a newly cycled 55 first. Check then out in MY TANK SETUP. Regardless of final stocking because I am doing a lot of moving around and of course I will not do anything reckless like moving a room temp betta into a 78 degree 55 with a catfish right off the bat but I was just wanting suggestions for my hardiest fish to put in first. Params are good to go just don't want to put in final stocking with out a tester fish. ha. Not that I expect it to die...
