I bought these fishes and the coral a few days before but I forgot to ask the guy what fish and coral they are
Can anyone help me identify the species?
Also the yellow fish has a strange habit of spitting water out of the tank, is it noraml???
i tried to take out the live rock in hope to manually remove them, but as soon as I took it out of the water, everything retracted and nothing can be removed...
When I left home this morning the live rock looks fine but when I came back at night I found some brown stuff growing on the rock. Can someone tell me what is it? Is it harmful for the fishes?
