I say you should do it...i'm biased though. They do look alot like that at this age now that I look at it haha. They are so fun, they aren't afraid of me at all, they eat out of my hand and follow the gravel vac when I clean. The only problem I've had so far is just hte fact that they eat 85% of their food in the water column. So rather than dumping in food I put my hand in the water and just slowly release some which don't get me wrong is fun but takes a while. I keep them warmer water but get really hyper after a cool water change so considering taking down the temp a little, which the firemouths would appreciate anyways.
