Hey all.. Had a sudden death in my tank today, got home from work and my midas blenny was dead, he looked healthy always swimming he ate alot.. Tested waters and everything is good. He did have moments where it looked like he was attacking the rock work but just thought it was normal.. Later on i kept an eye on the rest of the fishes make sure they look good and noticed a white dot on one of my clarkii clownfish.. i started the hobby and this tank about 4 months ago and haven't experienced any fish diseases.. Anyone know what that can be? And could it have been the cause for the blenny? Anything helps thank you!
