Is this a green bubble tip anemone? A friend of mine gave it to me yesterday saying it is a dwarf anemone but I couldn’t fine much info on that but also not very sure if it is a bubble tip anemone
never heard of dwarf anemones and majano's are not good. Either your friend hates you or doesn't know what kind of pest he/she is giving you. i would get rid of it. they grow like weeds and will take over your tank. If you want that to happen, keep it.
