Ive just been through **** transferring my 10 gallon to a new 12 gallon long dealing with a small cycle and losing some of my fish so I've been preoccupied with this tank and not doing much other then matience with my two 5 gal betta tanks. I was turning the lights off of one of the betta tanks and saw it....a black rose shrimp fry!!! I bought 7 of these online two months or so ago and 2 weeks ago I noticed one of my females was berried. The tank was due for a water change and I debated whether or not I should so I did a small one. She disappeared and when in saw her again I thought she dropped all of her eggs. I had bought a prefilter sponge, and a marina breeder box because I wanted to get the female in before the eggs hatched so my betta couldn't eat them. Needless to say I guess she had them. I rushed to put the prefilter on which resulted in tons of gunk from the filter dusting the whole tank and digging through the filter housing to rescue two fry stuck in there.. but it was a shrimp feeding frenzy so I'm gunna keep it like that and check the water params in a few hours. Anyways, this is my first batch of shrimplets and since I've kept cherries, blues, and now black Rose's I've never been able to get them to breed. My question is how many adult shrimp can live in my 5 gal? When the fry that survive get big enough can I put them into the breeder for a few weeks until they are big enough? It's a .5 gallon with the pump that recycles the tank water. My plan is to keep doing this and sell some and stock my 12 long with some. I don't mind my betta doing population control...I don't want to be a full breeder and have a shrimp-dedicated tank I think it intrigues his natural hunting instincts too. I just don't want a full blown explosion in a little 5 gallon any advice is appreciated!
