Hi Folks,
I have a 12 year old male RES, Tommy, who lives in a seventy gallon aquarium. A few weeks ago I noticed a film on his water. I figured his old Fluval filter might be causing it so I replaced it with a new Fluval filter. After a few days the film began to re-appear. Now, Tommy is fed in a differend tank to keep things clean. Is this film dangerious? It does not smell.
Thanks for your responses.
