FS: 10 Berghia nudibranchs
I have 10 Berghia nudibranchs for sale, they range from half to 1 inch long. First $100 in hand and local pick up in Calgary. If you don't want 10, please take all and split with someone. But you'll want 10. You're not buying 10 nudibranchs... but rather, you're buying a seed population to ensure they establish and breed for you. 10 won't eradicate your Aiptasia, but a population of Berghia will.
No shipping please, but if you find a local friend who can do that for you, go for it. Want to sell the lot. Background: I added 9 Berghia to my 27 cube on Sept 15. They disappeared for months until they finally hit full stride in their population growth curve. This nudibranch will readily breed on you as they are hermaphroditic, and a proportion of their eggs will hatch in a benthic larval phase ready for settlement. It is now end of Dec and I am seeing very few Aiptasia left, and they are now hunting during the day with prey being scarce. I am not a breeder, but I know that there's some left in my tank to take care of the remaining Aiptasia, and they'll likely perish after all prey are gone. If I catch more, I'll keep bumping the thread. I'm not a breeder (though you can easily culture them if you culture tanks of Aiptasia first). I hear many shrimp (including peppermint) like to eat these nudibranchs, you are hereby warned. There are 10 caught and floating in a bag in the tank, and I'll change water twice a day until they are gone, but expect these to go quick. I am home all day Christmas day. here's an article I published in Tropical Fish Hobbyist a long time ago about them. http://www.proaquatix.com/documents/Berghia.pdf Thanks.

here's a helpful graph. Often you hear people saying they put Berghia into their tank and they believe they're gone/dead but suddenly one day, months later, their Aiptasia begin to disappear and they see tons of Berghia out of no where. Shortly there after, the Aiptasia are all gone and then the Berghia crash & perish.
If you look at this graph (Green curve), see how the population stays low until exponential growth get into large numbers. For my tank, this is happening now 3.5 months after the introduction of 9 individuals in a 27 gallon tank. This can take even longer depending on your Aiptasia density, tank size, habitat available for settlement, skimmers, predators of Berghia etc. I do expect them to crash soon in my tank when the last Aiptasia are gone... they eat nothing else. by way of mention, for you dooms-day-ers... humans & earth follow this same exponential growth curve. Buy these berghia before the world ends. Thanks.
