the ones in pic two are nice but it looks like the zoos on the left are melting away. you might one to scrape those completely off or they will kill the entire colony. it's happened to me. better safe than sorry.
they was just open and hermit walked across them. some of mine have that brownish color when closed, but havent had a problem with them opening. i need to get better pic's they dont do them justice
:Up_to_som just dont tell my wife, i have 24 different one's so far. nothing super special, but slowly getting a wide variety, zoa's and shroons are just about all i will have in tank
