Zebra and Giant Danios are about 2-3 dollars a pop though bro. I'll figure something out. Oh and goldfish are not hard to kill well unless your taking care of them properly lol. Thinking maybe 2-3 little goldfish if they survive then I can always move them to my 135 gallon. I unplugged the heaters from that tank during my water change and never plugged them back in. Temp has been staying in the 70's on it's own.
