I think I had why too many plants in my tank. It is a 10 gal that I use for babies. I had it up for a year. Bristol Nose Plecos and fancy guppies were the occupants. I had a sword plant in Rockwool and an Anuebious on drift wood in the tank Bare bottoms. I bought a pair of swordtails. The female was pregnant so I put her in the 10 gal. I put a lot of floating plants in the tank to keep the babies safe. A few days ago I trimmed the plants in my other tanks. All were off shoots from sword plants. I have friends who wanted some. My baby tank had a lot of plants in it. The fish looked good yesterday. Today I go to turn on the light. All fish dead. I think it was lack of oxygen at night. I don't think the filter wasn't large enough to over come the plant load. Has anyone had this problem? I took the tank outside to clean it with the hose. I am drying it in the sun. Does it need to be clean another way?
