wabbitwuver, thats not healthy for ur fish. ur putting him into shock. & all those tiny bubbles make it hard for the fish to breath, because it sticks to their mouths & gills, preventing max. water flow.


dogs_4_me I think u can get a tiny heater (not a lamp) that will either hang onto the side of ur tank or sit at the bottom. for tropical fish (ur fishies). make sure the setting is in the green, mid to lower green is best. I find high green is too warm & they can get sick.

also get a small theomometer to keep an eye on the temp. during the summer add an ice cube to assist in keeping the temp down.
