I have a gold moly he is one of the first fish we got when we set up our tank back in june. Recently hes going threw these odd spells were he just sit on the bottom of the tank. The water is fine, he has no visible injuries or anything--no signs of disease If he sees me looking in the tank he runs over to greet me He does play and swim around the tank like normal He eats like normal within the last 2 months we lost 2 fish (both mollies).....1 of which was bought at the same time the gold molly was and was housed alone with the gold molly for a few weeks. The other fish we lost also a molly was the gold mollies little buddy they chased eachother around playing alot. So im wondering is hes just lonley because his friends are gone---even tho i have other fish (including mollies) maybe i should buy him a friend just like him?
