My son is at boot camp and I am taking care of his small coral tank. Before he left maybe around April we had an anemone in the tank but it died maybe the first week of May fast forward to June and a notice what sort of looked like brown sea weed or a plant that I couldn’t figure out how it got there then I went to feed the snails and noticed the “anemone” grabbing the shrimp pieces and upon closer look there were about 17 smaller ones and they are literally everywhere. My son is not coming back until next week and I am not even sure what kind he had.
