I am about 2 weeks-3weeks in having fish in the tank. got two clownfish the female is a frostbite bullethole and the male is a davinci. When i got the davinci he was missing a fin on his belly and had a red cut on the left side of his lower lip. over the past two weeks all that had healed up by itself. I am planning on adding some coral come this Tuesday and i was tinkering with my kessil. I threw it up on the gooseneck and turned it on just to see the tank with light for the first time. Immediately my davinci clown swam to the bottom and hid himself in a little crevice as soon as I saw this I freaked out a little. but as soon as the light turned off he swam back up into the current and was happy as a clam. my theory is the tank he was kept in had kessils on it aswell plus he was getting bullied in there pretty bad to be missing a fin and have a big gash on his lip. possibly PTSD? anyone encounter such behavior with clowns.
