Hello...my name is wendy and i'm new to ths forum and fairly new to the fish keeping world. I had a question for anyone out there that might be able to solve this mystery. I recently bought an albino pleco (he's about 2") for my 20 gal. The only tank mates in there at the moment is a blue gourami (3"). amd twp red platys. I just noticed tonight that he's not in the tank. I've looked everywhere - under the rocks, castle, behind the plants, in the filter system. Can't see him anywhere. Where could he have gone? Usually when a fish dies I see it laying on the rocks or up against the filter pipe. But he's nowhere to be found. Do this type of fish hybernate or dig under the gravel? I hope he's around maybe. He was really cute. Any help would be much appreciated.
