no crabs on my reef

[Triggreef]

Definitely no needed. I have very few stragglers from when I first started but I pulled most hermits out of my display for coral climbing. Hate that. I have some emeralds and a ruby mithrax for bubble algae but I don't think they really do that job well. Fighting conchs are my favorite snail.

My crabs have been nothing but trouble i exiled my blue leged crabs to my sump! he was dosile at first and then became nothing but a nuisance to my corals. Turbo snails are the way to go for dt ...

Fighting Conchs are my new fav also. I have 1 in my 40B. Awesome critter

Crabs are oppurtunists, if a nice peice of coral or a snail is the easiest thing to eat, they are going to eat it. Therefore they can't be trusted.

In my opinion crabs are not necessary for a healthy display.
The only ones I would consider are blue leg hermit and scarlet.
With the exception of acro crabs I have not seen one hitchhiker that is "safe".

The best CUC invert I have come across are the Hawaiian Strombus snails.
They stay small, have pretty cool shells and once established can reproduce in the display.

Do you know where you can purchase the Hawaiian Strombus snails?

I don't think they are necessary and from what I have read, many will pick at corals, and almost all of them will eat snails.

I didn't have any in my pico until recently. I picked up a blue legged hermit because I was looking to add some movement inside the tank. Corals are awesome, but they do kind of just sit there.
I went away for a couple of days, so I moved it to the sump because I wasn't going to be around to put everything back that it would knock or flip over and I am trying to get my ricordia that is splitting to attach to some rock work. That wasn't necessarily the best idea as I think the last of my dwarf cerith snails have now been consumed. But I have noticed a bit of algae that normally hasn't been an issue, I'm pretty sure the hermit has been keeping the algae at bay.

No more in the DT, they get too big and decimate cleaners. I just got the second one in the link tonight. He was in a large piece of rock that actually had a small tunnel system. Amazed at how many snail shells I found in there after getting him out. Well over 3" across .............
