aquactinics tx5 48" t5ho enough for crocea clams

[iverson387]

I have a 72 gallon bowfront and im looking to upgrade the lighting and have found the tx5 fixture for sale locally used. Would this be enough for a crocea clam if i keep it in the top half of the tank. i currently hace a 4x65 watt pc fixture and i could fit both of them over the tank if i have to. Will this be sufficient?

I have kept my crocea and maxima's at mid tank with aquactinics T-5 39watt. they are doing great and on both you can see good growth.Just bought a derasa and it's staring low in the tank. I would not try to keep a crocea under pc alone.Crocea are the most light hungry of all the Tridacnid clams.
