Too many?

Ok, I have a 20 gallon planted tank. 6 Green tiger barbs, 4 regular tiger barbs. I have two HOB filters. One rated for a 30 gallon, the other for 15 (Used when firing up the QT tank). I would like to put some Corys in there. I have shelter and a small cave dug out that I think they would find rather nice. Now I know corys like friends so I couldn't just get one or two, which means I'm probably starting to over fill this tank. Am I asking too much? If so, is there another bottom dweller I should look into?

The the calculator (adadvisor) in my signature to determine if the filters and tank will work with your stocking idea.

Thanks.
With what I want I'm looking at 128% filtration with 108% tank capacity. So as long as I keep my filtration up I should be good.

Your regular Tiger Barbs are too big for that tank. They also can be very territorial(leading to aggression) toward other species especially in a small tank like that. Lastly, Tigers are best kept in large schools which cannot be done in that size tank.

I agree with the above. Tigers are very nippy in lower numbers and will thrive in tanks of 40 gallon+

Can you get a bigger tank?

I have a 30 gallon and considered TBs when I was looking at stocking, but felt they needed more room than I could realistically provide.

Hmmmm... well that is problematic. Right now I have no other tank I could get. I have only the four regular tiger barbs and everything I read said they would school just fine with the green tigers. If I forgot the cory's and just left it as barbs would they manage?

The types of tigers is not the issue, The greens are simply color morphs of the regular ones. They are the exact same species, Same goes for the albino ones also.

The issue is too many fair sized moderately aggressive fish in too small of a space, Extra filtration doesn't remedy this.

They get too too large keep suitable numbers in a 10G:

Perhaps I'm wrong but... 20 gallon is what? 30" x 12" x 12" ?
As a species only for 10 tiger barbs that doesn't sound too bad to me. OK, granted a longer tank and 18 barbs would be nicer but wouldn't this work?

Those are the 20 Long dimensions, A 20g 'high' is 24" x 12" x 16".

Having said that, You might notice that directly above the video I posted I mentioned a 10G tank, I have no idea how that got in my head,

If you do this, Nothing else can go in that tank IMO.

Ah, well 850R, I knew they were the same fish, I just read a post wrong that seemed to suggest the greens didn't get quite as big as their normal colored brothers. Yes it is a 20 gallon high and I will hold off putting anything else in the tank until I can find a different home for the barbs. I am quite partial to the barbs, are there other barbs (besides tigers) that would be more suitable to my size?
