i feed them to my oscars and pufferfish and they both seem to really enjoy them.

if you have a 10 gallon tank you can keep ghost shrimp just about indefinatly. i would buy 50 at a time and put in that little tank and they last a long time like that. occasionally one would die but id always pick it out with the net and give it to my oscar. i had them mainly for my puffers but they both loved em.

i kept 1 small electric yellow in that tank for the longest time till it got big enough to eat the shrimp anyways lol, just to keep the tank's filtration good when i ran out of shrimps.
