i love guppies! a 20 gallon is perfect for some guppies! they come in so many variations colors and body/tail shapes! there really is so many you could have 100 guppies and none of them look alike (not in a 20 gallon though!)
I was at my local Petsmart today and they had so many different kinds of Guppies, I could not believe it. I agree with Josh, not because my name is Josh, but the variety of Guppies you could keep would be cool. Good luck deciding. I have an empty 30g tank and seriously cannot decide what to put in it.
I love my gold barbs and corys. The barbs are really active, school nicely but also have their own personalities and they just look awesome now that their color has really come in. The corys are also really active and goofy. The barbs and corys both love surfing the bubbles of the air stones and it's great to watch.
I don't like guppies because they reproduce so rapidly and I have no desire nor room to deal with fry. We have livebearers in my daughter's 20g because we didn't want to spend a lot of money on fish that might die since we were cycling with fish (didn't know about fishless cycling).
I agree with Ben above. The cories are so interesting, that you will watch them for hours. They are very active and prefer to be in schools. I have 4 in my 27 gal Hex, and it is quite comfortable for them. The nice thing is that you will find that the cories and the small schooling fish will inhabit different regions of the tank, which makes that combo really nice for balance.
First off welcome to fishlore! I agree with the cories they are probably one of my absolute favorite fish aside from some plecos. But here's some thing's I'd do with a 20 gallon
-6 snakeskin barbs
-4 Corys (my favorite are pandas but I think they may get too big I'm not sure)
-3 Mollys (I adore them as well, I'd go with three females of different varietys) or 3 female platys
-Snail for algea if needed
-10 neon tetras
-3 or 4 guppies
-Snail for algea if needed
welcome! i agree with the cory people. i love mine. i have a 20gH.....it's a good size for the 4 of them, but i almost wish i had a long for them. they are so cute. i also have
*6 galaxy rasboras
*6 harlequin rasboras
*2 male platys
*4 nerite snails(though one just moved to another tank to eat algae haha)
and i'm still thinking of a couple more i could get.
i'm not thinking guppies would be good, unless you have a plan for the fry. as well as platys i suppose. but if you do decide to get 3 female livebearers, try to get some that don't appear to be pregnant. otherwise they can come home preggers, and you have to deal with it.
I LOVE GUPPIES DD
&My albino cory's are always a fish we laugh at about how silly they are with their whiskers whn they suck things up
I also like Neon Tetras, But you need at least three or more.
Another old buddy of mine is the new "Glo-Fish". Brightly colored and beautiful. They swim really fast though. Balloon Molly's are also very nice but poop a lot! haha. They also become really aggressive if you put males and females together.
Finally, I like Platy's as a safe solution. Not many colors but they are nice traditional fish
personally I really reccomend bumping the number of cories up to around 5 or 6 they will be much happier in larger schools and I have heard some need the numbers to survive? I'm not sure exactly Mennu said something about it I just can't remember exactly, specifically pygmy cories.
I'm going to agree with josh11551 and Jrobber, and not because my name is Josh. Okay, it;s because my name is Josh too
I have to disagree with putting tiger barbs in a 20 - it's just not enough for them to live long term. I also would not recommend gold barbs for a 20 - they get much bigger than the store sells them. Cherry barbs are the only ones that are suitable for a 20 IMO, and I have a lot of experience keeping barbs.
I also don't think a 20H is suitable for corys, but again that's my opinion. And yes, pygmy corys have a tendancy to die off if not kept in large numbers.
I see that you've made your decision, which is great because its your tank.
My suggestion would have been cherry barbs, neons (cardinals) and guppies, with shrimp for clean up.
