Would it be a really bad idea to keep a breeding pair of BGJD's in a 40 gallon breeder by themselves? I do have a 140(48x26x26) that they could go in but I was hoping that I could try them in the 40 gallon breeder first. In the 140 they won't be alone and I really don't want them being bothered, or bothering my other fish in the 140. It will also be easier to get the fry out of the 40 and into their own grow out tank. Do you think it's one of those things that I could try with them, and if it doesn't work out just put them in the 140? They both seem to be fairly laid back and have never been really aggressive towards each other.
So, bad idea or it might work?
