Can I put any more fish in my tank?
 
Hi,

I recently bought a 20 gallon fish tank. It's dimensions are:

- 61.44 cm x 31.91 cm x 41.28 cm
- 24.1875" x 12.5625" x 16.25"

It's volume is:

- 75.7 L
- 20 U.S. gal

I also have a filter and a heater (set to 27 C)

Right now, its filled with:
- 6 Gold Barbs, each of which are about an inch long.
- 1 King Betta, which is about two inches long.
- 1 Siamese algae eater, which is a little over an inch long

What other fish can I add to my tank? Is there foom for any more?

I was thinking of the following options:

1) A single three spot gourami (moonlight, pearl, platinum, gold or blue); or

2) Six pearl danios; or

3) Six barbs (either Tiger barbs or Odessa barbs).

What do you think of these options? Which, if any, would work?

Also, if you have other suggestions, please let me know.

Please help me out with some advice.

Thanks.

You can put to your aquarium as many fishes as you want but this should last as long as you can keep condition of water in your tank stable.

Welcome to TFK, Gold Barb. Contrary to discusfishs' opinion I think you are already overstocked and have some potential problems with the way your current stocking is and I wouldn't add anymore fish at all until you get it sorted out. A true Siamese Algae eater will grow to six inches long, no question. I have them and they require some extreme swimming room (four feet!) and are also less inclined to eat algae as they get older, they much prefer what everyone else is eating. Tiger barbs wil never work in a 20 gl (most people will recommend a minimum of 55 for tigers). Perhaps you can take a look at our Tropical Fish Profiles (up top, over to the left) and read the info for each species listed? There's alot of really good information there.
Others will chime in with their opinions, I don't know much about Gold Barbs or King Bettas to comment on them. Once again, welcome to the forum and I hope you'll be happy here with us!

I agree with Aunt Kymmie, don't add anything else to your tank. You will need to find a new home for your CAE and your tank is too small for a three spot gourami, they will get to be about 6". Your tank is also too small for Tiger Barbs and I don't think they would be very nice to your King Betta once they got into the tank.

It's good that you are asking questions but make sure you do some research on your fish selection before you put anything else in your tank.

Best of luck.

I agree with what the others are saying about the sae, and I don't know much about the betta. I have a school of odessa barbs and I really enjoy them. They are very colorful, get about 2-3" and are very peaceful but active. You could also think about some cory cats and maybe oto's to replace the sae.

The Siamese Algae Eater is still quite small. He's no larger than any of the barbs, which are only about two inches.

At what point will I have to give him a new home? How long can I wait?

Thanks for your replies everyone.

My SAEs went from one inch to six inches in a little over a year. They grow fast.

AND they can get quite aggressive well before they are full grown.

Now is the time to remove the SAE. Fish grow continually and the environment around them affects their internal organ development. We can't see this externally, but as the fish grows if the environment is not sufficient in physical space and water quality (the two are linked) the development internally is frequently abnormal. In extreme cases we call it "stunting." The poor fish will have health problems forever as a result, and frequently die before its time.

When acquiring any fish, always consider its maximum size and other things like groups, and only acquire it/them if you now have the space required to later, or fully intend to have it soon. For example, the tiger barbs may "survive" in a 20g when small, but their growth is being affected by the confined space, they need more of their own to be "normal" in behaviours (at least 8 tigers). Not to mention that they are not "community" fish in the true sense. A group of 8 tigers in a 30g with maybe a couple bottom fish makes a fine aquarium, but that is very specific.

Hope this helps a bit. And, welcome to Tropical Fish Keeping forum.

Byron.

Just to add to this: My SAEs were never aggressive, not even now, that they are full grown. They like to school with my Denison Barbs, I have never seen a hint of aggression from them. Now, the CAE, that's a whole different story, very aggressive as they mature. Just had to clarify that as I hate to see a fish get a bad rap that's not deserved. ;-)
