Hi all!
I’m quite new to the reef tank world. So far I’ve kept a clownfish, favia coral and strombus snail on a 45 liter tank. All is well so far and water parameters are good. I’m now introducing a trochus snail, a skunk shrimp and a hammer coral. Different random algae has been growing on my live rock since the start, I guess this is normal but just want to make sure these are not pests. Any help identifying them is appreciated!
