Mine has done a great job (pinkish colored one). I'm actually considering trying to find rock that is covered in algea for him because hes been doing such a good job... rocks, glass he gets the job done
My cleanup crew in my tank consists of 3 urchins. I wasn't doing very good with snails, so I went that route. Works pretty good, and since my conchs are too big for them to pick up, it has been great.
I did my research on em and I found that you can supplement their diet with some dried kelp~also you can help their decorating musts by decorating them yourself~so with that I've actually covered him with a beautiful bunch of Red Caulerpa~so far so good he's left everything else alone~and yes I am finding bare spots on my LR after he's moved on~ where HA used to be~I did however add 3 more black turbos which are doing a nice job also~I know my HA issues are soon to be no more~Woot Woot!!!~I'll keep ya'll posted.
You will be feeding him soon I am sure, mine has knocked out most of mine and the coraline too in no time. If he is in your 8g, it won't take him long at all I am sure
will these guys eat the coraline off your rock too..i was considering getting one but if they eat the coraline i will have to pass..coraline just looks so cool.
