SUCCESS! since Sunday I was off; I released Sunshine(multicolor Angel fish) from the box early morning, sliding the box down the tank very slow and he just swim out. He hided on a rock until actinic lights went on. Dori (blue hippo) and first offender,was too busy fighting with herself on the mirror. Purple tang (Donatello) made sure Sunshine knows he's the king with a couple of chases, and flame angel (Poncho) had a couple of ugly confrontations until they picked right and left side boundaries. Yesterday the day was much better, Sunshine looks very happy and eating very well, tail fin healed completely. Than you guys for your help! Thank you Eddie! Should I remove mirror now?
