Dont be sorry. This is my first experience with a tank as large as this one. I am used to mollies, guppies, bettas and such. So I am a newbie in this regard. I just wish I could help the poor weather loach I have in this tank. Maybe the salt is causing his problem. When my parents had the tank they kept 2 tsp of salt for the whole 55 gal. I have no idea why. But I guess it is possible that it could be causing his problem. I will remove the goby asap and start water changes that are salt free tonite to see if it helps.
