100% natural tank?
I'm putting a critter keeper on my desk for one of my male bettas, but the configuration is such that a filter is not an option, nor is a powerhead. I can put only a light atop it-
I was planning to put about .5" of dirt, and then .5" of eco-complete (its what I have on hand; heard it works well) and then plant heavily with fast-growing stems (ideas on those species?), some java fern, some crypt wendtii, and this terra cotta head with java fern attached.
I'll do water changes as needed (probably weekly), it just wont have a filter.
tank is roughly 3g, light will be a 9w CF. obviously the only stock will be a male betta.
do you think this will work, or is it asking for trouble?
