My tank is coming along very well. I now have 4 guppies and 4 albino cory cats. I need schooling fish to "finish it off" I don't really care fore neon tetras and I really want schooling fish that tend to swim in the middle of the tank. I saw bloodfin tetras today but they where staying at the bottom of the tank, maybe it was due to the smaller tank size they had or the bigger fish in the tank? idk but if someone can suggest a schooling fish that will not swim at the bottom of the tank as much that would be great!

Thank You!!

Just for clarification, what water parameters and tank size are we working with, and is the tank cycled?

I have a 15g tall tank, something like 20inch wide and 18inch tall?? And I haven't cycled it yet, not to sure when to do the water change. The fish are all doing great though they eat when I give them food and they are calm.

I wouldn't add anything until the tank is cycled. You're just asking for trouble. Keep testing and changing water regularly until it is cycled.

After it is cycled, I would still be concerned about overstocking since you only have 15 gallons. Unless you only have one sex, four guppies will become lots of guppies very quickly.

Test daily. If you see ammonia or nitrites then do a water change. That's likely to be daily at the moment, since the plants I saw in your pictures won't help with it.

Fishy_pat made some good points. I'd agree with not adding any fish right now and that you might be overrun with guppies if you have mixed sexes (or even if you just have females since they can store sperm for a while).

Any idea what species you cories are? Or your PH or GH?

One thing I want to point out is, yes you have a 15 gallon, but surface area is more important than size. In essence you have a tall 10 gallon, as they share the same footprint. So you won't be able to stock as much as you might think you'd be able to.

I have all male guppies because I don't want to them to populate lol. And I didn't necessarily mean to add right now, I just meant for the future what would be some good idea's.

I highly recommend Harlequin Rasboras! Once they're settled into a tank their orange colour really shines in the tank, they look dull in fish stores but as soon as they're comfortable they look fantastic. With my group of 7 they are always together, I have 3 males and 4 females. Another thing that's pretty neat about them is that when they're "broody", two males will flare their fins together whilst swimming side by side in a display to prove they're the best male for the females. I've always been fascinated by the little guys, you will be too!

They look pretty cool from what I have seen. They only get about 2 inches in size so that's a plus

red eyed tetra, pristella tetra, male endlers, rummynose tetra, Rasobora's, danios, Penguin Tetra, Albino Buenos Aires Tetra, Congo Tetra, Buenos Aires Tetra, ect... All are schooling fish and would look good with what you have. Just remember you need at least 6 or more for a proper school.

I'm a bit worried about conflicting water parameters. Guppies prefer harder water than rasboras. Harlequins thrive in softer, more acidic water, and could have a tough time if your water is hard.

Can you get us the numbers for ph/gh/kh? They should be on your cities water supply website, and would help determine better fish.

I agree with BWG, your tank doesn't have much room for schooling fish as it's not even 2 feet long. Many of the suggestions I've seen are for fish that require a 3 foot tank or larger as they're active and can get 3 inches or larger. I'd suggest thoroughly researching each and every fish you consider.

Alrighty all sounds good. I have researched the fish I have put in so far and they are doing great but I am just not completely sure when it comes to schooling fish. I could get my cities ph lvl etc but I don't have city water I have well water and I assume that makes a difference? but who know's maybe not. If I don't really have enough room for schooling fish then what should I get??

So far you have 16" of fish out of 20" going by this will help you get started. 1" of fish per gallon that is if you only have a 20 gallon filter on and no real plants. If you up your filtration, add a bubbler, and add real plants you can add a couple more inches of fish. Here are a few you can get that go with guppies.

Dwarf gourami, Hatchet fish, one shark, or american flag fish.

Sorry I forgot it was a 20 gallon so ya you are at your limit.

Actually a 15g tall but I have checked on aqadvisor and I am still fine essentially.
