Are those the wide angle lenses?

I really like what kessil is doing.

Oh and what kind of a tang is that? A sohal tang? He looks absolutely beautiful!!

Yes, wide angle lenses. My tank is 48x24x24 and 2 kessil wide angles covers the whole tank nicely.

Yep! That's the master of the tank. Had him since he was a baby, about 3 and a half years now

Do you think they could be stretched out to cover 60" across?

My tank is 60x18x24 and I'm thinking about getting 2, with the possibility of adding a 150 if need be. I am not looking for a perfectly evenly lit tank but I don't want too extreme of a shadow. I'm currently using a 4 foot T5 fixture over the 5 foot tank and this has served me well.

Should be ok if you doing softies and lps. If sps, would suggest 3 a350 regulars( not wide angle ) if your tank is 24" deep. If your tank is only 18" deep, could possibly get away with 2 a350 w ( wide angles)

Would one a350w work well over a 30x30x12 frag tank?

12" deep? No problem.
