Hi,
I've got a male Betta that used to be fairly happy just swimming
around. The temprature and light where I live have started to
increase a bit and he looked happier. Unfortanelty I went away and my
girlfriend forgot to clean the tank. It wasn't that bad (one week, in
a fairly small tank, and yes I want to get a bigger one), however I
came home and he was floating on the top, leaning to one side (Swim
Bladder disorder?) every now and again. He seems to have gotten over
this in a couple of days, however a new "mental" problem has
developed.

He has recovered from this floating thing, but now is very "skittish".
Everytime I walk past he rapidly swims down the bottom of the tank,
slamming into the side or base of it trying to get away. He hides
down there when I try to feed him (have taken to placing food on the
top of the water and walking away). Its been like this for a week or
so. Starting to worry about whats going on with him. Is he still
getting over the problem eariler or has he developed a fear of me?

Thanks

Nigel
