Mike, As usual you have provided me with a thoughtful, informative, and helpful response. I had some reservations about posting such a winding and "personal" question on the list. Anyway, I am very diligent with my water changes, but indeed have not bothered to clean under caves. This particular tank is the only one where I have had any such (recurring) problem, but then it is the only one with macmasteri group apistos in it. I hope the rapidly growing survivor of the earlier brood is a female, because the male is doing quite well again. Thanks for your response. -Dan on 9/8/00 10:13 AM, Mike & Diane Wise at apistowise@bewellnet.com wrote: > Dan, > > Since no one else has responded, I think I'll give you my opinion.
