I put my name on a waiting list of 1 to 2 weeks for some berghia nudibranchs. there is 20 of them they are 1/2 inch an some will be larger. it is $150 dollars shipped here. thats about the cheapest you can go for that amount. I dont need 20, but i was wondering if anyone wanted some they can split cost with me for a couple or more that they want. Please contact me on here if you do, otherwise I'll just take my name off the list. The berghia are great for getting rid of aptasia. the berghia sell fast to if you are going to get rid of them later on. is want the supplier said. he says he usually has a 6to 8 week waiting list.
