So, if I have a ten gallon, with one betta and 5 ghost shrimp, I can get 5 more shrimp and still be ok?
the real anser is mabey it all depends. 1 shrimp per gallon is about the same as one inch per gallon.
if you are filtered and your tank has the floor space of a normal 10 gallon standard then you can put about 10 full grown female ghost shrimps in it most likely *if you get agressive macros weed them out* if you have decorations you can get away with almost 20 of them full grown *depending on size of decoration etc.*
ghost shrimp aren't like fish they don't need alot of room if you stock slowly as opposed to just walking down to walmart and saying gimme 20 *like i did* then you will be able to find your and thier own personal balance.
for example with my tank. i looked at my violet goby and saw that 3 ghosts weren't handling his left overs as fast as i wanted. so i looked at the floor space and said "wow i got room for like 20" so i went to walmart saw a fresh shipment of young ones looked at the guy working there and the conversation went like this no joke.
me: hi i would like 20 ghost shrimps please.
him: ? que honda?
me: grrrr... baennte camarons porfavor sinor
him: f*** ju wan twenty chrimps man?
. mushas grasias sinor.
after about 3- 5 minutes of catching and trying to count the right number of shrimps we both looked at each other started laughing and agreed 15 was a good number and the lady at the cash register could count them out if she didn't believe.
there were 23 in the bag.
*all spanish is spelled phonetically for those who can't handle that tuff i learned to speak it not spell it.*
