i bought some shrimp for my cichlids this weekend... they got eatten right away. they are 10 for $1.50. i have a 10 gallon tank that i have set up with a air pump in and some of the shrimp i have left... how fast will they reproduce? on ebay, they have a brine shrimp hatchery that you put right in your tank... does anyone have this? what does everyone els do about live feeding?
