No no, not all those fish were in the tank at the same time. The PH
, Nitrate, and amonia are fine. The tank is at my work, I check everything each Mon. and Fri. I replaced the Eel shortly after he jumped and I replaced the Lion fish a couple weeks after his demise. However, I may consider taking the damsel back to the store, she seems to want the area the Clown had always claimed prior to her arrival.
