Hello, I recently sent a message to LyndaB with a few questions about shrimp, after I learned that she was knowledgeable about them. She helpfully answered many of them, but she suggested I post the questions as a thread so that others could comment. So, here's the message: I currently have six Ghost Shrimp in a 2.5 gallon planted tank. I was kind of going off of Jeri's "cherry bowl" thread for ideas. Unfortunately I've read that you should only have one shrimp per gallon, otherwise fighting can ensue. Besides feeding time, I've never seen any issues, but before everyone has found their own wafer piece, I've seen one shrimp go after another (who has a piece), doing what sort of looks like nipping/pecking. Should I not be concerned about this? Also, I was wondering if it is possible to over feed shrimp. Obviously this can be a problem with fish, but it's hard to break an algae wafer into minuscule little pieces. Usually they're only about one square millimeter, but of course they expand in water. I sometimes get worried when I see one eating a piece for too long, and I always take out abandoned pieces so they don't foul the water. Are shrimp better at eating in moderation than fish? And finally, out of curiosity, I was wondering if you know anything about sexing shrimp (ghost shrimp in particular; I'm not sure if it varies between species or not). None of my shrimp have the characteristic saddle, and I'm wondering if the LFS had the genders in separate tanks and I got all males. In your experience, do females always have a visible saddle? Does it develop with Lynda said that I have too many shrimp in my tank, which actually fortunately won't be a problem. I wanted to keep some in my 10 gallon with a male betta, so once they start getting big, I'll move the largest ones over. This way, it will most effectively alleviate the overcrowding issue, and I won't have to worry as much about the betta eating them. Thanks for any answers you can provide! If there is anything else you think a new shrimp owner should know, please don't hesitate to tell me.
