Help! My male guppie wont stop hovering at the top

[Drlife202]

Hi,
Can someone help me please, I woke up this morning and I noticed my male Guppie wont stop hovering at the top of my tank near my heater, in the same place. I can't think what it could be, about 4 weeks ago I had to treat my tank for a parasite and also then had to treat for bacteria using melafix. But everything seems to have been going fine. I'm going to get my water tested at my LFS this afternoon. Hopefully I will find out what the problem is,

Thanks,
Sam

I went to my local shop, my water was tested fine. The women said that it might be because the fish is old, I asked I only had it for a couple of weeks, she said because that fish might of been interbread! I was like Anyway things seem ok now, she also suggested Melafix.

What temp is you tank at. Mine is next to a hugh window which is not a problem untill 30 below and colder. Then it is all my heater can do to keep up. The whole tank may drop up to two degrees at that time and the heater is on all the time. When this happens I notice my male guppies hanging around the top of the heater, catching the updraft of heated water.... Other possibility is that the current is a little slower there, the heater blocks it? I don't know just maybe.
