What a mess the lab space has become. I’m experimenting with different setups for the best long-term picture taking. The smaller the space I can confine the tadpoles in the larger they’ll show up in the pictures, but of course the space has to be big enough for them to swim, eat, and crap. Also, standard aquarium equipment (filter, heater, etc) is designed for larger water volumes than I’m using.

The solution I’m trying is to create a porous, confined area in a larger aquarium. The first attempt, a ’specimen container’ with holes drilled along the sides, hangs in the tank and works well but tadpole crap accumulates on the bottom and doesn’t make it to the filter. Also, bubbles from the filter get stuck under the container, making it difficult to get a clean shot. Now I’m building a mesh container that’ll also hang in the tank. Hopefully the waste will fall through the holes and I’ll be able to remove the wire-grid using background-subtraction techniques.

PS, Bug is fine.
