Bigger is better, but a good sized breeding tank would be a ten gallon. Won't take up much space, and can hold a lot of shrimp. If you want a spacier tank, a 20 would be great.
I want to start a shrimp project. I will need about 6 tanks. One for each species of shrimp. I will get some Red, Yellow, Green, Blue Tiger, and Crystal Red Shrimps. The one extra tank is just to separate the Crystal Red grades. I want to go with 20Gals, but their deepness is only 12inch. I would prefer 18inch depth. The 40Gals have 18inch depth, but I feel it will be a waste putting shrimp in a 40. I will use sponge filters in them. Will the 20Gals be enough to house say 100 shrimp?
i have my cherries in a 25 tall.. i think a 29 would be ideal and its where i plan to move them once i move some more fish around and free up a tank....
i had about 200-250 subadult-adults before their breeding slowed down..
Can you really house 200 shrimps in a 25Gal? If so, I might just get a couple 20Gals 24"x12"x16". I just want enough shrimps to maybe sell, trade, and/or use some as feeders.
with shrimp, bottom area is more important than swimming room of course. I'm not sure how readily available they are now, but years ago I used to see long tanks in 20 gal size. I think they were 20s.......... anyways
