my kribs have paired up finally in my 29g community. i heard that they can get pretty aggresive when breeding. so i want to set up a 10g tank with sand so they can dig and then i want to put upside down flower pots in it to.also some rosy barbs to be dither fish. will this be fine for them? is the size of the tank big enough? when they do breed what do you feed the babies? any tips on how to speed up the breeding?
