What to stock

[VFX]

With CUC, I find that I always need less than the 'recommended' amount.

For example:

J&L suggest this package for 180-240 gallon reefs.

150 - Blue Legged Hermits
30 - Red Scarlet Hermit
50 - Astrea Snails
50 - Margarita Snails
50 - Cerith Snails

I'd maybe add 1/2 or 2/3 that amount at first. In that way, if there's not enough detritus/algae etc. to sustain 300+ newly added inverts, you wont starve anyone.

You can always add more later if you find you need them.

.

Will they breed in the tank? can I just bring up the population that way?

To be honest, even in my old 15g nano tank, I never saw half my CUC once I'd put them in.

I don't know if they multiplied or not in there, well some snails did, but I don't think the ever hermits did.

margarita snails are pretty decent at scavenging, beware the price of turbo snails, they're good at cleaning but they're clumsy as heck, i'd still end up going for lots of blue leg hermits, they're pretty efficient imo.

I have had better luck with margarita snails then turbos. they are not as big do a fine job and do not knock any corals around. I have 12 margarita snails and 6 Turbos.(as of today i added 3 mexican)

Down side to margaritas is that my hermits despite how many shells i give them like to kill them for their shells.

As far as breeding in the tank iam not too sure only if they find a good enough hiding spot for the eggs. my sally lightfoot always gets my eggs even the ones i dont see. he will just come out from behind the rock with a sac. not sure but i asume hermits would eat eggs if they come accross them.

I would also put some scarlett hermits in just fora change of color.

+1 on avoiding Turbos...

I find Trochus, Nassarius & Ceriths do a pretty good job.

Guess i shouldmetion i also have some pyramids and dovetails.

Yes, I've found that the recommended number of CUC critters from sources to be too high.

In a newly established system there may be not enough food for all of those snails, crabs and especially shrimp (unless you feed them).

Eventually your CUC system will balance itself out and will only support the amount your tank can provide, in terms of food.

In a new tank, sand-dwelling critters (nassarius, conches) will be of little or no use, and would most probably die off.

If you're cooking rock, there may not be enough left on the rock to support a large CUC immediately. Wait until the algae blooms (which undoubtedly you'll have) settles down, then add your CUC.

Adding that many of anything to your tank will cause an amonia spike, which may kill the vast majority of your cleaners. I would wait until your live rock in is place before adding any livestock. That way you will have a buffer to counteract an amonia spike. After all, LR does most of your filtrating.

Sounds like it will be a nice system, with the solaris light and all.
