Mislead into a Jack Dempsey

I got a 20 Gallon tank for christmas, it's my first fish tank. I went to the pet store and got my first fish, thinking I was going to be getting a couple Tiger Barbs I was actually lead into the direction of a Jack Dempsey, I was told that it's maximum size is 6 inches and that the most aggressive it gets is nibbling fins. I get home put it in the tank and do some research and find out it's really aggressive. Due to this being my first and only tank I will not be upgrading, I don't see why a fish that gets 6 inches couldn't survive in a 20 gallon tank, it's not like it's tiny it's good size. My problem is that it's going to be so aggressive when it get's older I can never give it a tank mate. Suggestions? And no I don't want to kill the fish because some people don't think the tank will be big enough for him.

Hi and welcome to the forum.

Take the fish back. A 20 gallon is too small for a Jack Dempsey. Jack Dempseys grow to 8-10", not 6". A 24" tank for a 10" fish is cruel. There's simply not enough swimming space. They are also a messy fish with a heavy bioload so water quality will suffer in such a small volume of water. Do the humane thing and return the fish. If the fish store won't take it back, sell it or give it away on craigslist.

150 Gallon - Mostly American Cichlids
135 Gallon - Angelfish Community
75 Gallon - Odd couple (Polleni/Angelfish)
55 Gallon - African tank
20 Gallon Long - QT
10 Gallon - Empty

Welcome to the forum!!!! just a quick heads up no one here generally would suggest killing off a fish due to human error.. in this case the error of the fish store giving you inaccurate information.... i would suggest strongly either research a little before you get to the store or when you go create a list and head home for a little time to research before buying... and if at all possible go to another store and feel them out double checking their advice... while ther is no clear cut right or wrong there are some things that simply should not dont be done for the comfort and health of our pets..

I took it back last night, I was sad it was my first fish :(
I got 2 tiger barbs to replace it. When I woke up this morning I saw them floating at the bottom not moving at all and I thought for sure they were dead then I left came back in a few minutes and they were swimming around so they were sleeping. I'll be adding in 2 new tiger barbs probably Sunday to go with them :)

It seems that I have not cycled the tank since it's only been running for 3 days. I guess the best thing I can do right now is to hope my fish make it through the next month or two while all the bad stuff in the water goes away. I do have 2 testing kits to check the water daily as of now it's on the lowest ammonia level.
Should I wait the entire month or two to put the next 2 tiger barbs in?

i would test your water every day or two and do water changes if it gets to high (about 20-30%) untill you see that things are stable for a week or two (some cycles go faster than others) then add the other two .... this is just my opinion but it is also the best thing you could do to make sure you are successful.....
