I have lots of questions, but I’ll start off with a little information. I have a 36 gallon bow front, I have it had 2 clowns, lawnmower blenny, 2 cardinals, and a little golby, I also have a small clean up crew, hermit crabs, snails, and starfish. Ok, so I did a no no, I bought a tang didn’t quarantine (he’s going into a bigger tank). Now I’ve had him for 13 days and everything looked good. Saturday I did a 10% water change and Sunday I woke up and clown was acting up, I tried to isolate him and go to store and get some stuff for quarantine and by the time I got back he died, looked like Brooklynella. Long story short, I’m going on Tuesday and I’ve lost a golby, cardinal, and another clown. My biggest concern is how do I get what ever the hell is in my tank out? I’m going to quarantine the rest of the fish but don’t know how and why when they look good until it’s to late. HELP!
