junnie, didnt you have the same algae problem as I did? because I just found my goby and my gumdrop both dead. I think whatever is in my water (tap) may have done it... also, algae blennies dont do too well in captivity. my Gobies were extremely skinny as well, even when I spot fed him for 2 weeks straight daily. I think it is some kind of parasite in the water. good luck and I hope everything makes it ok!!!
