I got some ghost shrimp for my betta tank a week ago and am already having problems. I chose ghost shrimp because they are recommended to keep with betta because the fish can't see them as well and are less likely to pick on them. I asked for one shrimp but the very nice guy at the LFS gave me two (for the price of one). Anyway, after adding them to my tank I only ever saw one of them. I noticed that one of them had molted, and removed the exoskeleton (which was stuck on some java moss). So, one was MIA right off the bat. The other one I found dead yesterday, and still no sign of the other. The dead one had turned bright pink... does that mean anything or is that just what happens when they die? The one that has been missing could just be very shy and hiding very well... there are lots of good hiding places after all. But I have trimmed and moved plants around and seen nothing, which seems odd. Am I doing something wrong? I read up on them a little and found that they like temps of 65-82F. My tank is kept at 82F, which I thought would be alright but maybe it was too warm for them? Any other thoughts? help! I would really like to keep shrimp in my tank to help keep it clean and also because they are interesting and fun to watch... but I don't want to get any more if they are just going to die. Other types of shrimp might be okay with my betta, he's not super aggressive (actually pretty lazy), so I am open to other types if there are some that are better suited for a warmer tank...
