Setting Up A New 20 Gallon

I would like to set up a new 20 gal (long or high whichever is best for fish)
I would like to have something big, or as big as I can get and somewhat aggressive/personable (doesn't have to be aggressive)
The fish can be the only one in the tank that is okay.
Is there anything I can have? I haven't set up yet.

 

i would get a 20 long.
not sure what fish would work...

 

I would also get a 20 G long.

As far as a single showfish..I don’t know!

I’ve always had community tanks in my 20

 

What fish are u interested in?

 

Long is best for most fish. Most fish don't prefer to swim vertically.

Maybe look into Rams or Gouramis.

 

I would go for a long 20g. I would recommend something like the German Blue Ram.

 

I would get a dwarf gourami tank or a sorority betta tank in a 20 long

 

The problem with having a dwarf gourami is the Iridovirus disease. You might get lucky and have a health fish but its sadly very common for the fish to die.

 

I recommend a long, and maybe you could stock some sort of ran cichlid. Killifish are fun too!

 

I wanted like just one sole chiclid in that tank. I don't really like dg and I already have rams. Would any short body work? Or a pair of blue acara?

 

You could possibly do a planted tank with pea puffers.

 

I say 20 long and that being said a betta sorority or gourami. They are labyrinth fish meaning they breathe atmospheric air. They would love a 20 gallon long.

 

A single electric blue acara might work. You could also try kribensis, flag acara, leaf fish, or betta macrostoma (giant betta).

 

maybe. My lfs has had a 10 gallon tank whit some rhodes/peacock (i think) cichlids but idk if they will work. Can i have 1 or 2 in a 20 long or a pair of acaras? And the puffers need snails right?

Can i do a short body cichlid? Like GT, JD or Flowerhorn? (Short body)

 

All of those get too big for a 20 long. Even if their bodies stay stocky, many cichlids produce a lot of waste. I wouldn't keep a Flowerhorn in anything smaller than a 75, personally.

 

I will have a filter rated for a 40gallon tank and only one of them will be in the tank alone, I thought that short bodies stay much smaller

 

A flowerhorn still wouldn't fit. They need a LOT more space.

 

Betta Sorority would be a fun way to go, it gives you the color and personality that you seem to be looking for, without having to only have one fish, or worry about it out growing the tank

 

How about a pair of rainbow cichlids?

 

Oh, i only wanted 1 or 2 fish so not really a sorority. How big do rainbow cichlids get?
I can't really find them around here.
