20g, how would YOU stock it ?
 
Let's say someone gives you a 20 gallon high tank, complete with lighting (2x13w CFL), HOB filter and heater. There is also play sand (tan) in it. How would you stock it ? What plants would you use ? What type of landscape would you go for ?

As you may guess, I have recently acquired such an aquarium. I am not in a hurry to set it up, and would appreciate your ideas. Look at it from a brainstorm perspective. In a few weeks when I'll be setting up the tank I'll create a thread for it, and you'll see how it turns out !

Edit : forgot to say, water is fairly soft (5dGH) and slightly basic (pH 7,4)

Knowing your water I would add some driftwood; heavily plant it with low tech plants like anubias, and pennywort, and java fern; let the tank mature; and stock it with some kind of small tetra like cardinals or neons (mosquito rasbora or dwarf rasbora would also be neat). I would either do substrate fish like pygmy cory or dwarf cory or oto catfish or have one centerpiece fish like a honey gourami. If you do the small rasboras, the gourami wouldn't be a good idea as it would probably eat them. Basically what I'm getting at is a soft water nano community.

I would suggest much the same. I would also replace the filter though, the current from an HOB in a 20g will be stronger than any of these fish appreciate. A simple sponge and air pump, or the internal Fluval U1 will be adequate.

The pH will almost certainly lower below 7 as with a GH of 5 d the KH/Alkalinity is likely low too. So soft acidic water fish are the way to go, and there are so many small species that would make a beautiful 20g planted display.:-)

Gaaaah you and your water! So jealous!
I'd do a cool water set up. Heavily planted, with maybe a third more open with big smooth river rocks. That side would have more of a current, but it'd be less where the plants are.
Around 13 celestial pearl danios, and 2-3 of any type of hillstream loach.
I'm not sure how well CPDs handle currents, but they are river fish I believe. The loaches have high oxygen needs and need a filter rated 40 gallons on high flow.

The hillstream loach would be fine, but not the CPD in water currents. As noted in the profile, they occur in boggy areas and ponds. One of the problems of finding fish to work with these loaches is the current, plus the cooler temp together.

Well in that case white cloud mountain minnows like current, correct?

Yes, that is the only match I can think of, though there obviosly may be others.

If it were me and the water parameters allowed it I would do this:

1-2 Kribensis Cichlid
7-9 Cardinal Tetra
6 Kuhli Loach

Do that with some nice live plants, driftwood, rocks and black gravel. *drool*

This is only a 20g tank the OP mentioned, so the kribensis pair would fill it (males reach 4 inches, females 3) and they will spawn which means nasty to other fish. And there is no room for the poor cardinals to escape to in a 20g.;-)

The kuhli would ensure no fry resulted from the spawnings, if that is wanted.

Good point....The males do get fat.

Cichlids and their amazing spawning skills hahhaa.

It would work with just one female though, and if you kept 7 cardinals it would be a lil under stocked and if you kept 9 it would be packed. I'd keep plants ofc.
