I just set up a used 29 gallon tank last night and let the sand settle, and acclimated my betta, Ahti, to the tank this morning. He's currently swimming around the entire tank and investigating.
This is my first community tank, and as soon as I get some live plants in, it'll be my first planted tank, too. (other than the marimo I had in Ahti's old tank, which I later removed when they weren't getting enough light)
I'm planning to put 4 otos, 4 peppered corys, and about 6 harlequin rasboras in along with Ahti. I've just shifted his decorations and his old filter cartridge in to help kickstart the cycle, and I had some start zyme that helped tremendously in getting his old tank cycled. Well, cycled as much as a 1.5 gallon can be :P
Ahti's in there right now, and I'm thinking of getting about half of the harlequins while we're out shopping today to get a bit more life in the tank without stressing out the BB too much.
There's plastic plants in there right now, but I'm hoping to eventually replace most or all of them with live plants. I tested them, and they're all rubbery, not hard plastic, so I figured they're safe for the time being.
I also want to get rid of the small plastic pile of rocks decoration that was in his old tank, which I only put in there right now because it's got a lot of algae and diatom growth on it and I want that to spread for the otos before I add them in. To replace it, I'd love to get some mopani to really add some pop, because I saw it in person at the local Pet Supplies Plus in their tanks and just wow, it looks stunning. Way better than in pictures.
I don't have a test kit, and my parents are totally unwilling to buy me one, so I'm going to have to just be fairly conservative and cautious with adding fish. I'm hoping that having old filter media will make it easier to get going and not lose too many (if any) fish.
I'll update later today with pictures!
