after the male has bred should i cover the tank with a blanket but still allowing sun to shine because my betta fish is really aware of the outside world and moves away from the nest. i noticed this when i was in bed the other night and wasn't moving and watched him swim away from the nest trying to get at something. so should i cover next time.
( btw in other post i exxagerate of do not think of what i am typing so if i do that please try to re-word it in your brain and do not write bad comments about me.) ( people know what i am tlaking about)
