Need help stocking my 30g
I currently have my 30g stocked with 7 rummy nose tetras. I want to add neons, zebra danios, guppies, and possibly swordtails. How many of each do you suggest? Thank you!

Rummy nose tetras get to be about 2 inches, so that's already 14 inches of fish. Danios get to be about 3 inches, so you could maybe do five of them and you're done. They're a schooling fish too so they need to be in a group. Same thing with neons. Don't know much about guppies and swordtails. I'm sure someone else will chime in.

Guppies and sword tails are live bearers so don't get males and females and remember that they need hard water while the tetras prefer softer water with a low ph. I would go for 7-9 neons and either a small shoal of 3-6 cories or a BN pleco to keep the substrate clean. You could also get a male and female honey gourami if you wanted

I am a huge fan of livebearers but agree with the others that their preference for harder water make them poor candidates. Swords are extremely active and dynamic swimmers, but they need to be in a longer tank than this for you to see what I mean. I never kept them in a large enough tank, I think, and mine are currently in a 55.

I like the idea of perhaps two groups of tetras of distinct color and shape. Too many assorted schoolers looks like a jumble. I agree that you might also concentrate on adding surface and substrate-oriented fish so everyone keeps out of each other's way. Small ancistrus (bristle nose pleco) or dwarf chain loaches, maybe, hatchet fish maybe as an alternative to a small gourami species.

That'd be a very busy tank.. I wouldny suggest it. I have a 28 gal with 11 rummys and 7 harlequin rasboras (and some corys and a gourami) and that's really all the schooling fish I'd be able to stand.. my tank is already quite busy. I had three schools of fish at one point and it just looked like a mess. I'd suggest only going with one or two groups of schools, unless you're getting something like corys for the bottom or hatchetfish for the top..

Also, rummys need very soft water which is not compatible with swords or guppies. I would also suggest cardinals instead of neons because they are usually much healthier and hardier. I want to say I even had rummys, neons, and danios at the same time and it was just crazy swimming all over lol.

You should also start by increasing your rummys to at least 9, these fish to best in larger groups, even larger than most other tetras and other schoolers do.

If I could redo it, I'd probably go with a larger group of rummys and something like hatchetfish instead of my rasboras.. even though I absolutely love my rasboras so I will not be giving them away.

I forgot to mention that I already have 7 pepper Cory's. I was just listing my swimming ones because the corys are in the sand digging around most of the day. So I wanted more mid and top level fish. My rummys don't swim much. For 6 months now they swim a little and hide the rest of the time. They are all about 1.5 inches long. I want more fish that will be active swimmers. I was happy when I first got my rummys but they always hide its annoying. It's like something scares them even tho I am never really around the tank. There's nothing to be afraid of.

get more rummys and they wont be as afraid, try doubling it - when i went from 7 to 17 harlequin rasboras there was an astounding difference

Cardinals like their water on the warm side, which is why they are often paired with discus. I take it they do well for you,Jennesque, but all my friends are having trouble with them!

I agree with Varkolak, that a larger number will result in more natural (more pleasing) behavior. And since his water seems to agree with rummynoses, why make it more difficult than it has to be but adding a new species?

The idea that 3-5 tetras can constitute a "school" is laughable. These little guys routinely travel in groups of hundreds if not thousands. I think a school of cories and a school of Rummynoses sounds altogether beautiful. Possibly hatchet fish as surface dwellers. Possibly. Much of the art of fish keeping is knowing where to stop!

Byron has even recommended cardinals over neons. Neons are grossly interbred and therefore have a very week gene pool. I only suggest cardinals because they are so similar to neons in color and behavior and much hardier. There are many other tetra to consider.
