hello Finatic,
Thanks for the reply! Temp is between 76-78 degrees. The PH is 7.0 . I noticed also that they don't seem to like the light. When the light is off they both (glass cats) swim around and seem to be okay, but the minute I turn on that light, the either hover near the top facing away from the light on the oposite side of the light, or as soon as I turn it on, the darker one always lays on it's side on the bottom. The other clearer one then just hangs around the darker one. I will take your advice and get more companions for both species. I'll give that a try today and will keep you posted!
Thansk, Annie
