I dont see what is wrong with my stocking, the tang was tiny and was going to go in the 265 once it was setup, if my valgmii hadnt died, i wouldnt have gotten the sailfin.
Now that I think of it your temp could have been a problem I normally keep my tank temp in my reef setup around 75 to 80 I mostly try to keep it at 78 I do think that 84 to 85 degrees might have been a little to high but who am I to say !!!! I am saying this because 24 gallons is a very small tank and I believe that a temp that high might not be a good idea for a tank that small.
too much fish and aquapod's are killing machine's they get way too hot and the chiller is terrible that they sell with it. I would sell it and get a nice 75 gallon tank with overflow's and build your own setup and stop losing money in the all in one death trap.
