Checking on tilapia light/photoperiod and will report back. I know BG/RES are spawned indoors with artificial light. ML I thought I saw lights in the tub? If you have to rely on indoor light that clear plexiglas cover you had in one pic will do ok .

Some good info here but not a direct answer. Still looking.
