Ok, I originally had started setting up this 10 gallon tank awhile back for some tiger barbs. it has a heater a decent filter a rock that has place to hid underneath and somepretty good fake plants for hiding. BUT everyones been telling me that i cant fit enough tiger barbs in there for them to be comfortable and happy. new idea. this weekend my stepmother lisa found a pretty big crayfish in a flower pot under the flowers. after releasing it into a decent size stream/large puddle i had remember seeing electric blue crayfish at a lfs!! what im trying to ask is if it would be ok to put at least 1 blue crayfish into a 10 gallon with a good amount of hiding places and such. also what they would eat and there tank mates. it would be great if someone could post a link for crayfish from the internet. any comments welcome.
