My husband purchased a betta from the pet shop and they told him that bettas liked cold/room temp, murky, stagnant water so he did not purchase a filter or heater. After visiting this site I went to the pet store and bought a heater but have read that in small tanks (we have a 4 gallon) a bubble or power filter can upset them. So, I bought a couple of live plants to aid in keeping the tank clean and the water oxygenated.
The problem is, I can't find a good way to anchor them! They just keep on floating up to the top. Does anybody have any suggestions about how to get my plants to stay put??
