I have a 18 gallon reef aquarium with 26 lbs of live rock, I also have aqua clear 300 running with reef carbon in it and i have a Seaclone protein skimmer that can handle 100 gallon tank. i have had it going for 7 weeks now. and all my tests are perfect (0 nitrate) (0 Ammonia) (0 nitrites) (PH is 8.2) I use RO water for my water replacement. I have 7 hermit crabs that are doing great, and four trubo snails that are also doing great,and i have a tiger striped serpent sea star that is doing great, and i have a bulb anemone that is doing very good to, my calcareous algae in purple and in pink and in green is growing fast the tank looks great. my question is i have two Ocellaris clowns that i recently put in my tank one has developed a what looks like fin rot on lower fin he keeps it tucked up but he still acts nomal he stopped eatting but i noticed today he act like he want to eat that is a good sign. i think it was caused by stress, and was wondering if i should just let it go and hope he comes out of it.
