yup

Guppies. Get all females. Male guppies are like a less-aggressive sorority (<--- Quoting Sakura). And if you get males and females you'll have a lifetime supply of fish. If you need any help determining genders, I can help.

 

[finnfinnfriend]

What about fish that I can keep singularly or in a pair?

 

[MaisyDawgThirteen]

Well, bettas obviously. You could try a dwarf gourami or a honey gourami in a 15 or 20 gallon. I don't know much about those, though.

Have you looked into dwarf puffers? ADORABLE. You could do 5ish in a 10 gallon. They need a somewhat densely planted tank, and pond snails.. They need to eat snail shells regularly to keep their "beaks" trimmed.

+1 on the Dwarf Puffers, but they need lots and lots and lots of plants or decor to break the line of sight between each puffer. They get quite aggresive with each other, so with all the live plants you'll break the line of sight. They do best in tanks that have diffused lighting so get lots of floating plants and they also do best with little to no current, so baffle your filter. What I suggest, if you're interested in these guys is that you set up one of those tanks, and do a NPT, let the tank go through a silent cycle. Also, don't try to remove any pest snails and let them overrun the tank. It'll be free food for the puffers. After the cycle is done, introduce the puffers to their new home, they'll thrive.

Or you could try Betta Imbellis, they are wild Bettas and they can be housed together, males can be housed with males and females. They like diffused lighting, they feel more safe and secure that way, also little to not current as well. Planted with low light plants, with lots of surface area and floating plants, they'll do well.

 

[Olympia]

Just a note that wild betta need VERY soft water (under 6gH for most species).
The reason I could not keep them ;(

Thank you!

 

[Mo]

Your welcome. I had made that a while back as thread

 

[Bombalurina]

There are just so many options. What sort of combination are you looking for? Centrepiece+school? Just schoolers? Just a couple of unique fish?

Just a couple of unique fish or just one single specimen

 

[Bombalurina]

Well, that gives you some fun options. You could have:
- a dwarf puffer tank
- A pair or trio of ADFs
- A pair or trio of killifish (I really like my fundulopanchax gardneri)
- A honey gourami
- 3-4 male Endlers Livebearers

FYI, not all fish in that list are advisable for tanks under 20g. Many of those fish are schooling fish, some needing larger schools that require more space. Many of those fish are very active fish, needing more swimming space than a 20g (or less) allows.
For example, many people think that because Neon Tetra are small that they can be kept in small spaces. This is not true, they need more swimming space than one might think and should not be kept in anything smaller than a 20g tank. Or, as another example, many people list a 20g tank as the minimum for a group of Bloodfin Tetra. But after having kept them myself and seeing their full size at maturity (more than 2", almost 2.5") and seeing just how active they are, I would never recommend they be kept in another less that a 3' tank, at bare minimum. Even more, Red Eye Tetra (Lamp Eye Tetra) get almost 3" and are just as active. They should never be kept in a tank under 3', preferably a 4' tank.

So... Just FYI. :-D

Well that's why, once I decide what species I want, I'm going to research the particular species, just like I do with every pet I get.

 

[finnfinnfriend]

What about Long Fin Red Minor Tetra?

 

[Jessicatm137]

They would probably work, they are also called more commonly called the serpae tetra.

 

[Olympia]

I'd keep that species only, I hear they are aggressive little buggers.

 

[Jessicatm137]

I agree with Olympia.

 

[LittleBettaFish]

In a 15-20 gallon tank, I would go for one of the Pseudomugil species. There are several species to choose from and some prefer soft water, while others prefer harder water and some even brackish.

I have honey blue-eyes and they are truly spectacular when displaying and sparring. If you want them to spawn, all you need to do is add a spawning mop or a handful of java moss, give them lots of live food (I do blackworms, grindals and BBS) and they will usually do the rest. They are egg eaters so you need to comb through daily and remove any eggs for artificial hatching.

In a tank that size I'd recommend a school of delicate, spotted or forktail blue-eyes depending on your parameters. Forktails and delicates are more suitable for harder water and higher pH, while spotted and honey blue-eyes do best in softer and lower pH water.

Here's a picture of a happy 'frisky' honey blue-eye male

You could also try a small school of Melanotaenia maccullochi might work in a 15-20 gallon tank. They don't grow very big, and the Skull Creek variety is absolutely stunning.
