i had glass shrimp reproducing in 55 gallon tanks... until the crayfish took over..
gravel bottom, sponge filters, water lettuce, anachris, duckweed growing.. once i noticed a female glass shrimp in berry, i started feeding the tanks a little green water every couple days.. the instar are really hard to see, but i would find them on the water lettuce roots most often.. gotta have the green water to get them started.. i've seen small ones (less than 1/8")eating a (frozen) blood worm..
