What and how would you do with a 20g?

[DiscusBR]

Hi folks,

I have a 20g sitting idle at home. It is too small to work as a breeding or hospital tank and I am considereing setting it up for smaller fishes, like rasboras and may be a betta. I am planning a sand substrate, a piece of manzanita and maybe some hardy plants, like anubias. I wonder if you can help me decide on:

1. Population: what fishes would you have in a 20g?

2. Filtration: I have a canister and two sponge filters in my 80g, but I don´t know what would work for a 20g. Would a single sponge filter be enough?

Thanks in advance.

Over here,20galH is pretty standard to use as a breeding tank.Three of my pairs are in 20gal right now.

Another option would be heavily planted with a school of cories on the bottom and maybe 1 school of tetras in the upper zone. I personally like large numbers of fewer species rather that a bunch of meandering un-related fish.

I have a larger 26g that I can use for those purposes. I have Cuipeua discus and folks here in the forum have said wilds prefer larger tanks for breeding.

That sounds good. I agree that few-strains-tanks are more interesting. What about having a beta? And what about filtration?

Do you already have a hospital tank?

You can use it as shrimp tank with moss and sponge filter or HOB filter :)

A breeding pair of Discus LOL and a sponge filter would work fine.....Josie

An experiment tank! testing out different filtering techniques, water chemistry, lighting, plants, fertilizers, foods endless possibilities....

Yes, the 26g.

Sorry, I am no big fan of shrimps, unless they are in my dinner plate :p So would a sponge filter sufice? I am no big fan of HOBs.

Josie, I am just a humble beginner :) I only have one 80g tank with 7 wild Cuipeuas. Two of them have paired, but no eggs yet. If they make it work, I will transfer them to the 26g. I do not have room or extra tanks for another breeding project.

Huumm... Sounds interesting, but too complicated :)

Sorry I was just kidding, I like the idea of a shrimp tank.......Josie

If it is a 20G long, I would recommend some shell dwellers from Lake Tanganyika. I prefer Gold Ocellatus as I currently keep them in my fish room. Lots of good color and personality. They don't need much room to thrive. A simple sponge filter and weekly 20-30% WC's will keep them in great health. Feed once or twice a day in very small amounts. Water temp 78 deg. F. Tap water treated with Prime or SAFE.

Easy! I'd plop a sponge filter on it and add a daphnia culture.

yes, sponge filter is good enough for shrimp tank.

A pair of any apistogrammas and a group of small tetras(cardinals or flame tetras). A well planted 20 w/your water parameters that you listed in another thread would be perfect for apistos.
