:sad I have lost more fish 5 clowns. I cannot figure out why I cannot keep clowns. I have one Sailfin Tang (1-2 weeks) I Lawn mower Blenney, (4 weeks) 2 Firemouths (?) (1 week) I dont know if I'm starving my Fancy Serpent Sea Stars 2, and they are killing them or what? Or maybe a poisenious coral or what? I was able to find two clown and take them out but the others are in the LR or something? I'm going tomorrow and purchase a Magnesium test kit! Help!!! :sick:
