I've done a lot of reading about this, and there seem to be a quite a few (too many) options to consider when beginning a planted tank. I currently have 2 female bettas left from the only sorority I've ever had that are currently living together with a separator, and they are both about 3 years old (the older fish died off). I have a medium sized apartment, but not too many places where I could put a medium sized tank (5-15 gal) and absolutely nowhere that I could have a larger tank.
I would like to know If there is any practical way to start a planted tank with a 5 gal tank and two female bettas. Right now they are sitting on a shelf next to my desk in my office where I can keep an eye on them, and their doing well. But everything is plastic, and I just can't help but wonder if they would thrive better in a more natural planted tank. I want to have them for as long as I can, and give them the best quality environment to live in as I can, (and I don't know if their just getting older but a while after I split them up because I was down to 3 bettas they don't seem as active or playful). I just have no Idea where to start with a planted tank, and I heard that they can be fairly tricky to get just right.
I would like to know what your opinion is on a 5-10 gal planted tank. I know the smaller the tank size, the bigger the risk when it comes to water quality. I also would like to know how (if possible) to create a planted tank specifically for bettas. I'm not sure if I'll ever try a sorority again, but I'd like to give my current bettas a nice home.
Are there any plants that bettas specifically like to nibble on? Are snails a good addition? And what kind of gravel/sand/soil is best suited to bettas?
