Hi everyone, and thanks for your comments and suggestions. Lowie is still not looking well I purchased a heater and continued regular water changes. I got my water tested and it turns out the PH level was too high (7.2) I believe, and the water was very Hard. Although the person that was helping me out did not really know what to suggest for the hardness. Any suggestions? Lowie has his off and on moments sometimes he just sits there and his small lower fins look clamped. I'm worried.

I really appreciate the helpful suggestions. Thanks.
