baby Derasa and 27W dual PC

[colourmop]

my friend's tank crashed yesterday and he put his baby derasa in my 12 gal (dual 27w PC and dual 27w actinic) just wondering, will it hurt the clam? (tissue damage due to over streching the mantle) i will get a 150w 14000k MH on tuesday, will it cause any permanent damage to the baby clam?

As long as your paramters are fine, the deresa should be ok. The MH will be better for it though. I don't recommend clams under PC's but many have done it just fine.
