i currently have gbt anemone, crocea clam, long-tentacle toadstool, yellow tonga leather coral, mushroom polyp, birds nest coral, favia morph, and i believe a small frag of acropora. can all thier nutritional requirements be satisfied through photsynthetic algae or should i be feeding with something. right now i focus on feeding the few fish i have and just maintaining water parameters. all coral, fish, and inverts in my tank seem to be healthy and happy. lighting is 2 150mh and 2 130watt dual actinics for a 55 gallon tank. replies appreciated!
