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.
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.
Personally~if he gets rid of the HA~he can eat all the coraline he wants~my HA is so bad in spots that the coraline cant compete with it~besides coraline is replaceable!!!
