A few weeks ago I got a cheap betta on an impulse buy at the pet store and now it's escalating into more stuff haha. But today I bought a cheap 10gal glass tank with the intentions of putting a divider in (maybe divide it more later) and putting another fish in.
Right now until I make a divider I have my betta fish in it. I just cleaned it with the glass tank sponge thing that is made for it and then filled it up, put the couple of plants in, and then conditioned it. Is there anything else I'm supposed to do to make it better for the fish? That's all I did with the last tank (1gal) and he was happy.
Also for the bottom should I use rock or marbles?
