In your other thread, you mentioned the green horn to be free to good home, right? If so, I'd be more than happy to pick these up from you pending pics...
As long as my conditions would support them that is... I currently have a 30 G long with a 175W MH light over it, it's not a huge amount of light like some of these 400W setups I've seen, but the tank is only 16" deep with a 3" sand bed. Would this suffice?
