Egg-laying air-space aquarium MOD

Postby mvigor on Mon Aug 14, 2006 3:13 pm

I designed a modification to my glass aquarium lid that will let me completely fill the aquarium with water and still give my apple snail a place to lay her eggs. This tank is going to live in a Kindergarten classroom all year.

Edit: I forgot to mention it initially, but this modification can be used with the light strip and a HOB in place. It stays safely open in the raised position when you want it to.

Custom cut glass was $3.

And the other. I did clean the silicone side. LOL!


After I took these pictures I removed it again to cure for a couple more days. It's going to the classroom late this week!

Excellent! I've tried doing something like that but not with very much success, I'll have to see about getting some glass cut :)

If you have a plexi glass shop in your town, 90% of them have a scrap bin, I built a whole sump for a 30gal out of scrap plexi. Its super easy to cut exactly how you'd like with a hacksaw, dremel or whatever.

You can even get it in different colors!

After using this design for a couple weeks now the only thing I would change about it is the need for ventilation. I've had two clutches laid on the glass in this air space now, and without removing them they would never dry, not even a little bit. Even after a week the "Snail Glue" (as my 4 year old called it) was still liquid.

A couple vent holes drilled in the glass with a skinny bit on a router press would work, but I think I'm going to try running an air pump airline into the side of the lid and dehumidifying with outside-the-tank air that way.

The issue of humidity in the air gap wasn't really as much of a problem as I initially thought. I was right in thinking that a person couldn't really leave the eggs in there to hatch because after 2 to 3 days they lose their grip, break free and slide off. However that's not a problem to me because well before that time I would have already decided if I will be moving them to a hatching tub or destroying them.

The glass isn't still foggy like it was at first, that passed within a couple weeks and it has been very clear for a year or so.
