Given that tiger barbs need much larger, yes it is overstocked now.But is it overstocked now?

Tiger barbs can get 3-4 inches when mature. Plus they're shoaling and semi-aggressive so need space.
And clown plecos though they're a smaller pleco, do poop a lot, so a 20g is already pushing the limits bioload wise.
And a single swordtail. Swordtails can reach 6 inches long, they are also active. They need a minimum of 55 gallons or 4 foot footprint.
A few in some of my livebearer groups, not as common with the common species, but still has the potential. But the potential to grow large is there. They're also somewhat social and does like to have a few companions around, so a 20g is really really pushing it either case.Swordtails almost never get to 6 inches; but they are large. I have them in a 29 right now. My 5 year old male is well around 4 inches including the long sword. Having said this I don't disagree that it is heavy stocking. Of course there is an open question if it is a 20 long or 20 high. I think a single swordtail in a 20 long is fine - btw have you ever seen a 6 inch swordtail ?

The ones I've seen that large have been the males with the long finnage, though I've seen some wilds grow massive as well, but chances of this one in this thread being a wild is extremely slim.That's one giant swordtail. Was it male or female? I've had swordtails (red velvet) off and on for 30 years and they all mostly seem to reach the same size (around 4 inches). Was yours a wild strain ? Mind you in my 29 i have 4 females and 2 males and yes it is a bit on the crowded side as swordtails do prefer more swimming room but I remember when we had a tank in the dorm (20 long) and started with 2 and by the end of the year had over 30.... oddly those 30 were not nearly as crowded as the 6 i currently have but whatever.
The sword tail is doing fine as I have said many times and not showing any signs of stress and you tend to exaggerate a lot none of my tiger barbs are palm size unless your palm is the size of a toddler
I agree one swordtail would be fine and I have removed any plans for more fish@NoodleAquatics is correct that as the barbs age they will be a problem; and I would agree that they should be removed esp if you intend to add more fishes. I personally find swordtails not so finicky but that doesn't mean all fishes are not finicky; this is in regards to both aggression and being stunted by a smaller tank. This is both a good thing and a bad thing but regardless to debate over a single swordtail is a bit of a distraction. As to whether you do or don't remove the barbs that is your choice.
Like I said removed any plans for fish ,please read all the post thank you very muchWith the bioload from the pleco and swordtail, the barbs are pretty much maxing the tank. Adding a school of cories is just going to be bad for them. Eventually your barbs will get bigger and start beating up anything slower and smaller than they are (in a tank that size).
