I don't see anything wrong with that tank size. He's tiny. Just keep an eye on water params incase you get any spikes, but as long as he's eating you should be fine. When I had baby rhoms they would love live blackworms... but as long as he's eating I think you're good. I love how aggressive they are even though they're that tiny.
Yea i know! Seeing him attack bloodworms is hilarious! Hes got some serious courage for being 1/2"! I love this guy!
Water is perfect! Just added a huge piece of dw in the tank today. Nitrates under 10ppm
