Well it took a week before my pygmy angel decided it would be fun to harass my new clam. It has spent that past two days pretty much closed up. I put together a mesh cover over it to allow it to open and receive some light without being harassed. I have a 3 gallon tank lying around that was used for FW. I'm going to turn it into a reef and move my clam over there. I've been trying to think of the most economical and best way to light this little tank. The small 6'' T5 that came in the hood would heat the water up in the summer, so I'm thinking LED is probably the best bet. I figure a BoostLED par30 bulb will definitely be enough light for my crocea clam and might be the best bang for my buck at $74.99. I could do a DIY LED setup, but I have no clue how many LEDs I would need and if it is even worth the cost. I would love any suggestions you guys may have, especially pico reef keepers.
