Hermits & DSB's

I read that hermits will take all the beneficial organisms out of the sand bed. Is this true? If so, what should I use as a clean-up crew in my aquarium?
 
I just read in the new Reef Keeping Magazine that hermits eat most of the microfauna in the sandbed, as well as snails sometimes. Same thing with the sea cucumbers- eats all the good stuff.
 
Bump to learn more.

I have read conflicting information on this as well. Some say no crabs or bottom dwellers because they eat beneficial organisms but others say it is good to add them.

HERMITS ARE NATURAL CLEANERS OF THE TOP OF THE SAND BEDS....1 PER GALLON ALWAYS
1 per gallon always? advice in stocking fish or inverts that deals in absolutes is generally always bad advice. no one keeps the same type of set up. whats right for most is not right for all. and lots of people, like me prefer mostly snails and other inverts to do the cleaning because i find hermits can be too destructive. the few i have love climbing my sps for no reason. they are also active scavengers, so i would see how having enough hermits would keep certain types of life from living in your upper sandbed.
 
I read that article also. I feel this is an advaced topic because most are saying hermits are fine for a deep sand bed, contrary to what is stated by Tom Murphy in his article about deep sand beds. Ron Shimek also has the same type of advise.

Personally I don't know but am very interested in this topic. Interested because it is going against the norm.
 
Also, I was wondering, are Pepermint Shrimp safe for a DSB/Fuge? I just found about 10 Aiptasia on my newly introduced LR ruble from Premium Aquatics. I was thinking about the Aiptasia eating nudibranch, but there pretty expensive for there size, and might just get killed right a way. Whereas the pepermint is a little more robust and hardy, cheaper, and I hear it can be a effective Aoptasia eater. Another plus would be is that if I got 2, they might breed, and introduce more eggs and larva to the water colum, helping to augment the fishes diet (or else I might get baby shrimp).
 
peppermint shrimp eat the smaller aptasia very well in my experience. As far as them being safe to your sand bed, I don't know. I read in an article I cannot find that shrimp will eat inhabitants of your sand bed. A good way around this, is to have a rfugium if possible.
 
Everything eats something else. Variety, and moderation help to make it all work ;) A couple of small hermits will not eat more sand bed critters than can reproduce, a couple too many and you have problems. Same can be said for many other critters such as shrimp. Some will be utterly devastating to a sand bed critter population even with one, such as large hermits, sand sifting stars, sand sifting gobies, etc.
 
Would 2 Pepermint shrimps be fine in my 12"x18" refugium/DSB? It sounds like the shrimps aren't bad for the DSB in moderation, I just wanted to make sure I don't overpopulate my fuge with shrimp. And if the fuge did get overpopulated with shrimp, would that mean they would eat all the micro critters, like the sand sifting sea star? Thanks for the help.
 
I wouldn't add anything to a fuge that eats critters ;) Part of the purpose of a fuge is to act as a breeding reservoir to help keep the main tank populated ;)
 
Oh yeah, one more thing. I have Aiptasia on the rocks in my fuge... how would you reccomend getting rid of them? I think there is about 10, mostly small except for 2.
 
I've good luck with kalk paste. Make up thick slurry of kalk, turn of the pumps for an hour or two, inject the aiptasia and leave a thick blob of kalk on top as well. Let sit for an hour or two and than turn the pumps back on. Some of the larger ones, or the ones well buried in some crevice might take a couple of treatments to do them in.
 
Thanks for the idea billsreef. Do you have an exact "recipe" to make the kalk solution? Where could I find something to inject the anemones with? Also, I found this idea that uses natural Aiptasia control. You put the Aiptasia infested rock in a 5 gal bucket, and introduce a couple of Pepermint shrimps. The shrimps seem most likely to eat the anemones if they cannot find any other food, so they would be fed very lightly if at all. After 2 weeks I would return the rock to the fuge, and keep the pepermints in there for a week or two just to make sure they got everything. After that the shrimps would be removed & I would introduce a detrivore kit from Inland Aquatics. Do you think it would work?
 
Basically just kalk powder (or Mrs. Wages Pickling lime) and water to make a thick paste. The injection part can be troublesome, I use old syringes from Salifert Test kits.
 
I have never injected the paste into the aptasia. I just turn off the flow to the tank for 10 minutes or so and when everything calms down I slowly drip the paste right on top of the aptasia with a syringe and encapsulate it. Seems to do the trick for me. Let it sit for 10-15 minutes before reintroducing the flow. Occasionally I have also siphoned out the kalk and aptasia after a few minutes to prevent a kalk overdose.
 
Would aiptasia be a bad thing for a sump?I was always under the impression they were good for nutrient export.
