I bought the tank after my boss had it for about a year or so i left about a 1/3 of the water in the tank and got home filled it the rest of the way up and put the two fish that were in it when i got it( picaso trigger and spotted grouper) had them about a month and decieded to get a lion fish, he got stressed and died and the trigger tried to eat him so he died too at least thats what the guy at the fish store told me, so waited another month with just the grouper he was fine, then got a clown trigger he didnt last but about 4 days he had white spots all over him that i was told was ich, then the grouper died a week later and now im here with nothing but snails and hermit crabs
