Trumpet snail exodus
I've just seen the most amazing thing, and I'd like to know if there's a
reason for concern. I have a small recently planted tank (20g). I switched off the light, and 20 minutes later there are 50 trumpet snails "beelining" it to the surface along a congested path in the middle of the front glass. It looked like a highway during rush hour. They were even releasing their offspring as they went. By the time the adults reached the top, there must have been 20 young snails mixed in with them. I really wish I owned a digital camera. All this occured on a path that was no wider than 2 inches across. I'm concerned that since I started a Hagen CO2 system today that the water parameters have changed too drastically. My Ph went from 7.6 to 6.4. I added the plants 2 days ago, and I know it affected my Ph. When I woke up yesterday, my clown loaches were poking out the top of the water (apparently for air). I immediately turned on the light to hopefully start the photosynthesis process. My loaches used to come out all the time when I had a cheapo 15W fluorescent. Now, they hide all day with the 55W PC I have running. It seems that most people advised not to try to stop the CO2 at night. With a yeast system, this seems impossible anyways. I was wondering if it would be beneficial to turn on an air stone from a pump though. That might help. I definitely didn't enjoy the sight of my clowns bobbing for air come morning. Any advice would be appreciated. |

I don't know if there is really any reason for you to be alarmed; I was just browsing through the Baensch atlas and the section on trumpet snails says this is just what they do. "At night they will collect on the glass just beneath the water line..." Maybe they were just following one who knew the way. Erica http://members.aol.com/_ht_a/mitoem/mitoem/index.htm |
