I dont know if maybe this is the wrong place to post this but anywho. I bought some Cons to raise and breed for feeders. expecting to have a few months to wait before anything happened I was shocked to see baby Cons hatched in my tank. I wasn't watching them that closely but one day I noticed a pair was really agressive and thats when I spotted the fry. I let them grow out for a bit and once they where free swimmers I moved them to a cycled 20Gtank ( I could get them all bu once the parents where removed they disappeared quickly) they still had their yolk sacks but I got prepared and bot a shrimpery allong with the packages to add in with the mix. The LFS told me that in a day I would see them and just to dump the little bottle in the tank and refill with tap water. all's well so far but after 2 days no more shrimp where appearing in the top. well I let it go for a day but when there where still none I emptied it and restarted. same thing again I only got 2 days out of a package before the shrimp quit. one more time same effect. whats going whrong or what am I doing wrong? all the help is appreciated.
