So after giving up on getting cutteri for my breeding project, I decided to go with rainbows. They were my second choice. I was having a hard time finding any for sale that were large enough to sex, so I went with a 10 pack of juvies for $15. My problem is I bought a 30 gallon for a pair I thought I would find. So my options for now are to grow them all out in the 30, then sell off or rehome the other 8 if/when a pair forms, or take my best guess at gender and put those 2 in the 30 and the rest in a 75 with a 2” buttikoferi (I know, I’m getting him a bigger tank in 6-8months) for a little bit and see if any pair up. The rainbows are in the 1-1.5” range. Which option should I go with or what are some other options.
