cindyp Posted April 24, 2015 Share Posted April 24, 2015 hello all! i have had no luck on my tank thread. this thing is deep maroon in color and started out thinner and a horse shoe around this particular zoa stalk. now, a month or six weeks later, it's grown into a giant donut around the zoa's neck. the zoa still opens. but i'm thinking it is a parasite and no good, and will cut it off? or try to? some suggest just cutting the zoa off. does anyone know what this is?

Snow_Phoenix Posted April 24, 2015 Share Posted April 24, 2015 Looks like some sort of sponge or tunicate. Does it react when you poke it? Any chance you could ease it off the zoa? Link to comment

Any chance you could ease it off the zoa? i have not touched it. but i plan to today or tomorrow for the next tank cleaning. i was gonna KIIIIIIIL IT! no? i'm not a fan of sponges--but i only had the very invasive encrusting kind--clear white jelly fingers. ugly.

metrokat Posted April 24, 2015 Share Posted April 24, 2015 Chop off the polyp. It's a sponge. Link to comment
cindyp Posted April 24, 2015 Author Share Posted April 24, 2015 Chop off the polyp. It's a sponge. thanks, kat. i've read much sponge love online as filters, but i've only found them to be parastitic and invasive! Link to comment
jamescstein Posted April 24, 2015 Share Posted April 24, 2015 The back of my AIO is filled with pineapple sponges.. They can stay, as long as they stay back there. Link to comment
ajmckay Posted April 24, 2015 Share Posted April 24, 2015 Oh Snap! I have a few of those on a zoa rock I just got... They aren't near the polyps yet, but I was wondering what it was. Initially I was hoping it was a scutus or something but it didn't move. When I touch it it's smooth and rubbery feeling. The rock also has other more obvious sponges in it, but the side opposite the zoas. Link to comment
amphipod Posted April 25, 2015 Share Posted April 25, 2015 Probably just chance it grew in that location Link to comment
ajmckay Posted April 27, 2015 Share Posted April 27, 2015 I took a pic of mine... Strange that we're both seeing these strange sponges right next to zoas. Also as you can see I apparently lied in my initial response, it's right next to some zoas and it's obviously blocking their colonization. I'll probably try to remove the sponge soon before it gets any bigger. Also I apparently got a few hitchers on this rock... A chunk of zoas from the middle disappeared the other day - found them a few rocks over, attached to a bivalve of some sort that apparently wasn't happy where it was. Link to comment
