Whats running this tank?

Theres a few key items to my terrarium. The main one is the water. Then theres the 25watt heater to keep the tank from freezing over, and last, the powerhead which creates the fountain. I have a switch on that so at night I can sleep quitely. Then there are the lights too, which total 45watts.

Filter

The filtration is not all that complecated. All it is, is a sponge that filters the water before it goes to the powerhead. No carbon, nothing special, just a sponge. Then there are the plants which do help with filtration.
Heres a list of plants. Ill add scientific names as I can find them.
Ricci
Java moss
Java fern
Anubias nana
Some type of grass like plant
Various crypts
Some unknow plant(yeah, you know what plant that is)
Mangrove soon to be added as it arives in mail

I like tires.

Toads name

The toads names are B1 and B2. I bought B2 before B1, so there is no order to there naming. Its just after those bannana in pajamas. See, heres the quick story behind there naming. At one of those George Web's dinners, there is this B1 and B2 statue that me and my friends are trying to get. Thats the story.
