i got a RBTA 3 days ago, it seems to have lost some of its color comapred to when it was in the store. i am worried it is not getting enough light at the bottom of the tank. the tank is a 50g(18" tall) lights are 250w 10k MH (store also had 250w). should i be worried, maybe point a powerhead at it in hopes it will move higher?
