I turned his light on this morning and no Waldo! He was laying at the bottom of the tank. So I opened the top to feed him and he didn't move. I thought ok he is sleeping but 4 hours later he has only moved a little and is laying on his plant. He looks really swelled and his eyes are swellled as well. His ph was fine monday and I checked it today and it was between 7.6 and 7.8 so I added decreaser to the tank to bring that down. His tank has problems with brown algae and I can't get rid of it. I have done water changes, cleaned his castle and plants even added the worthless algae tablet and every week it is full of brown algae. I am getting ready to move him to the betta bowl once the water heats up and break the tank down and scrub it and run boiling water over his castle and plants. I am just worried he is beyond help!! He won't even flare at himself now. The scales around his face are very light now. He is a dark red so they really stand out. What the heck happened to him over night? I have some meds that I can put in the tank once I clean the algae out for pop eye and such. Any suggestions or is Waldo on his way out?
