Okay so my sister got a 29g high tank and her and her bf aren't sure what they want. Oh it is also has live plants. The tank is almost completely setup just missing the heater.
Some rules: No male bettas, no sororities, no neons. If all the fish listed are compatible with a female betta, they might get one, not sure. If the betta doesn't work she will go into my sorority so yeah.
I'm in the process of stocking my 29 gal. Bombalurina actually listed all of the fish I'm looking at (except the Mosquito Rasbora (Boraras brigittae). Right now my stocking plan seems to be cardinal tetra and some kind of gourami (probably a small group of honeys) and kuhli loaches.
You might also want to talk them into getting floating plants, too. A lot of those fish appreciate floating plants, especially gourami.
They could also get two ryukin goldfish (the other breeds get a little too large for that size tank), but they would need some pretty heavy filtration.
To bombs suggestion, I wouldn't do an angelfish, Bosemani Rainbowfish, or Serpae Tetras. Angelfish will be lonely without some company and can't go with anything else. Bosemanis get too big and need to be in schools. Serapes tend to be aggressive with other fish in anything less than a 55 gallon. You could have a nice Kribensis in there, but only a single one. You could have a nice school of terra and some Cory catfish, depending on the substrate, with a single Krib. Be sure to only get one, they get aggressive when they breed.
I am trying to get them to get some peppered cories, the substrate is sand btw. The filter is up to 50 gallons, but they don't want goldfish.
Is this stocking too much
10 rummynose tetras
maybe 2 honey gourami, if they end up with two males will they fight? If they get a male and a female will they breed?
If they're going with honey gourami it is best to get either one male (as gourami do get territorial) or one male and 2-3 females. There is a chance they will breed, tho. If they are sure they don't want any babies it might be best just to get one male. Two males would probably squabble too much without any females around.
That actually sounds similar to one of the stocking plans I had for my 29 gal (except I had loaches instead of cories). The rummynose are really nice looking fish that school very tightly. They really will want to look into getting floating plants to dim the light for them, tho. Rummynose and gourami like subdued lighting and will show much better colorings with it.
At those stocking levels with regular water changes and live plants, they should be fine. If they want to play it safe reduce the rummynose to 7 or 9 (schooling fish look best in odd numbers).
I gave them some of my floating plants but I don't have enough to make a huge difference. Once more of my plants grow out though the floaters get sent to them. Okay maybe I will run the gourami with them. What about 11 rummynose, 5 cories, and a female betta? If she doesn't work out she would then go into my sorority, if of course they decide on the fish I think are good for beginners.
