So, my 20 long is in a weird place. I have 4 Colombian tetras (definitely adding more) and 3 glowlight tetras (I'd love to rehome them but can't so they will be staying here until they die out, will not replace). I was going to add American flagfish due to my hair algae issues, but have not been able to find them for MONTHS in any of my LFS. Just looking for ideas, I suppose. My temp floats between 74-76. The only idea I'll be saying no to is any kind of cories/plecos/loaches, just not my style. I'd love to have another fish with a HUGE personality like my old GBR but my water is obviously way too cold for one.
