The lighting is a 30w T8 with an aquarium reflector base. I know I need more lighting (its on my wish list). I thought the GBTA would hang out at the top of the tank till I got upgraded but its happy as a pie and moved from the top where it put it to mid-tank. I have no coral (other than a mushroom that came on LR
) Everything looks happy in the tank. My mushroom spent a day or two stretching out for the light but I moved it up about half way and she lays out beautiful now and if I leave the lights on later at night she will shrink up to say "i've had enough".
