Bubble Tip Anemone
No, this is not a Ritteri. young Bubble Tip Anemones have bubbles at the end of their tentacles, but as they age, those often go away. This anemone is over 13 months old, and soaked up the light from 165w PC lighting. I used to feed it meaty foods every three days, but I backed off as it grew too large for my 29g tank. This is a fairly hardy anemone, but it needs good-to-great water conditions and adequate lighting(VHO, PH or MH). It may consume phytoplankton as well. Reef-safe.
Here are a few pictures of it in the earlier years.
