First let me say I just got a used 120 gal tank I didn't do this to the poor fish I just want to help it. When I got to the ladies house she said she has been trying to sell her house and she left the fish tank at the house she was selling. For 2 months she just cam every other day and fed the fish and added water when needed. The fish had no lights what so ever on for those 2 months. The tank water was horrible There was a dead bat in the protein skimmer etc etc. I just want to help the fish if I can. There was a blue tang in there also and it didn't make it, all the others made it 3 damsels the tang a clown fish a banded shrimp and a black urchin that will be gone today as I gave it away, 3 red legged crabs. They are all doing great but please tell me what I need to do I don't have a QT tank yet and I am not adding anything else until I get one. My water is perfect it is eating well doesn't act like it is sick comes to the glass everytime I am close. I am going to turn this tank into a reef with coral live rock etc etc
