I have a 3 month old 38 gallon IM with with 40lbs of mature live rock and 40 lbs of "live" sand. I bought a white glider ladder goby (sleeper blue dot) about a month ago. Noticed the last few weeks that he's wasting away. I've tried feeding mysis, cyclopees, brine, flakes and fish eggs. He eats everything but is still losing body mass. I've read this particular species is tough to keep. Shame on me for not doing better research...shame on my lfs for selling this fish into a known knew setup. Bottom line I'm looking to try to save him or give him to someone with a mature larger setup so he can feed himself. Any advice would be appreciated. I live in Jupiter FL and would be happy to give him to a larger tank in the area. He filters the sand all day and keeps my tank immaculate. Hate to see him go. Btw...I bought a yellow prawn goby at the same time and they hang together in the same hole...he's doing great. Any thoughts??
