hello, so on may 9th i got a black clownfish and an orchid dottyback. they are the first fish in my tank. i have a 10 gallon (but planning on upgrading to a 20 long within a month). anyway, the first day I got the clownfish it ate a little. the clown is very small (about an inch long). anyway, the past few days, (I've fed only frozen mysis btw), it has eaten a little but not as much as I thought it would. like it takes one or two pieces of shrimp and just lets the rest float around the tank. it does show interest in food tho, it comes up to the food but then backs away from the food after. i think it might not like the mysis i am unsure tho. its swimming just fine (although its swimming up and down a lot like everywhere in the tank but I'm pretty sure that's normal). it takes like a quick 2-3 min break max on the sand bed then goes back to normal. should I be worried?
