Ghost shrimp: details and snails
Posted: Sat Apr 30, 2005 9:13 pm
[img]I started with 30 CRS (which went up to 120+, dropped to 6 juvenile shrimp total, due to things I was learning, and is now back at a carefully watched and slow-growing 24 shrimp. (will have to think about getting others to supplement the gene pool as they grow up.) I'll have to post all the sordid details about the CRS, but along the way, I had some interesting things occur with ghost shrimp.
I was getting LFS feeder ghost shrimp for my angelfish...(I've had one sucessful breeding from angelfish which I raised to adulthood; angelfish can be work!) With what I was learning from the CRS, I decided to let some of the feeder ghost shrimp breed so I would have a constant supply. Set up another tank with foam filter (used an established foam), and tossed in a few females carrying eggs. When the females dropped, I'd remove them to another tank, (after seeing a few isolated instances of cannibalism of floating babies.) Java moss, some hornwort, and a well-established substrate later I had more ghost shrimp than you could shake a cichlid stick at.
Ghost shrimp soon ended up in all my tanks, including a brackish water tank with bumblebee gobies and young flounder. They didn't do badly in there, and continued to breed as long as I'd remove the females to the afore-mentioned tank to drop, then move them back. Seemed to suffer no ill effects going from brackish to freshwater so suddenly, either. [That's nothing I'd try with my cherries, though!] My brackish water tank has a sand bottom for the flounder, and a snail problem (like my other tanks.) I usually take care of too many snails in my tanks by smooshing them on the glass, and letting cordydoras cats or ghost shrimp fight over the smooshed snails. Ghost shrimp will 'smell' them from across a tank, converge, and fight over them to see who gets to suck out the algae-guts. Try it, they LOVE smooshed snails.
Not too long ago, I noticed whole, empty snail shells littering my sand tank bottom. (now freshwater again, as the gobies and flounder eventually died and I needed another guppy grow out tank.) I thought I was getting a snail disease. It was mostly the smaller of the little brown ramshorn snails, and the little pond snails, not the adult ones, and soon there were only 3 adult snails in that tank. Soon, I had no small snails in that tank, and was adding snails in from the other tanks, to fend off a growing algae problem. But it was looking like I couldn't keep a snail alive in this tank.
One day, I put about a half dozen small snails in the sand-bottom tank again, and had time to watch my tanks. I saw a large female ghost shrimp descend on a snail, and I watched her turning it over and relentlessly picking at its trapdoor with her feet and mandibles until she could get to the soft bits, by which time it was a goner and she was soon sucking it up. I nearly had a cowfish! This act was repeated by some of the other adult shrimp, with smaller shrimp crowding around and hoping for leftovers.
I have since seen this occurring in my other tanks. I have made sure I keep a handful of ghost shrimps in each tank to munch on snails. They can't eat the older ones, but at this point they are helping to keep the smaller snails under control.
