Yes I have shrimp available. Price is still as per page 1. I don't do recommendations per se. It's all a question of how often you want to see the shrimp and how patient you are. Some people get them strictly for algae control and are looking for 4-5 per gallon. If you have that much algae, I suggest alternate ways of controlling it. Not that the shrimp won't help, but neglecting aquarium maintenance isn't healthy for any inhabitants. Plus, the shrimp will show better color in a better environment.
Anyway, if you have a 55gal with lots of hiding places and fast fish, you won't see 6 shrimp very often. A few months down the road after they have bred and you have babies half grown, you'll see them more. More time, more shrimp, more sightings. If your fish are community fish and do not bother the shrimp, you'll see them out and about. Just remember, this is a shrimp that doesn't quite get 1 inch long when full grown. Alternately, you can buy a dozen or two and will see them more often.
