barnacles... some Q/A

[neoginn]

Is it possible to buy barnacles for an aquarium? If so where can they be found?

I've never seen any for sale, but I do know that barnacles are hard to keep alive in an aquarium. They are filter feeders and require a lot of food. I had a lot on my live rock when I got it and I think there may be one or two left (out of probably 100) after 2 months.

ok, thanks for the info.

I agree. I have never seen them for sale either.

just my imagination speaking but would it be possible to put like 5 fish in a 20 gallon then a barnacle to "filter" thier mess? (if five fish is too much just one or two trigger fish would do)
once again this is just my imagination.

[newfound77951]

Barnacles don't filter detritus (fish poo), they eat phytoplankton and zooplankton and other microscopic critters. So that would likely not work.
