8 gal biocube question

[acpoweradapter]

Ive got a 28 gal JBJ with some montis and a deresa in it. I was going to move them all to an 8 gal biocube and I was wondering what light I should get to go over it. No fish will be in the tank, only some sexy shrimp and maybe a fire shrimp with the coral. Is a 70 watt good enough or should I go for a 150 like in the jbj. Only thing is I keep the montis in the bottom of the tank, any higher and they white out. Any good light recomendations?
Thanks,
David

either a 70w or a 150w will work on the 8 gallon. the 150w mite be alittle to much lite with curtain things. height, heat, to much wattage based on height.....if there bleaching when you place them high. they mite be getting too much lite. it can happen. rare but can happen
