Is there a difference as to how many fish you can put in a 27 gallon Square tank verses the Hex? Some one told me because of the less air space on top and the deeper the tank, the less fish you could have in it. Is that right? If so how many would be a good idea? Thanks for any help you all can give. God bless

Howdy, and welcome to fishlore! I have a hex tank as well. The surface of the water is where gas exchange takes place. Since the surface area of a hex tank is smaller than that of the same gal./rect. shaped tank, the bio-load must also be smaller. When I was reading up on all of this stuff, I learned that the surface area of a 20 gal. hex is roughly equal to that of a 10 gal. rectangular tank (so about 1/2). So, for a 27 gal hex, you could have about 13 in. of fish (if you're going by the inch/gal. ratio). Now, there are ways to slightly increase your gas exchange, thereby increasing how many in. of fish you can have. If you have bubblers of some sort, it aggitates the surface of the water, increasing gas exchange. I have 3 types of bubblers in my tank. So you can get by with maybe a few more in. than 13...just use your good judgement.

The information you got was right. Hex tanks carry less surface area so you can have much fewer fish.

hi, what kind of fish r u going to keep in your tank? angels would be a great choice. they love taller tanks..........

ChiLady

Aren't angel fish a little harder to keep though? I have platys and am pretty new at this. So I worry about getting other fish that are more sensative.

I have a 28 gallon hex and my angel is perfectly fine. I got it when it was a tiny little baby(the main body was about the same size as a dime). Just do wht some people call the drip method. If you don't know what that is, just search for it in the thing at the top and the started by was me. If you do that, the angel should be fine.

I love my angels, they're not hard to keep, but I wouldn't put more than 1 or maybe 2 in a 27 gallon. the only issue you might have is if they pair and lay eggs they can get aggressive towards any other fish. But they like tall tanks, and would do great in a nice tall hex tank.

Tom

I forgot to mention that. Thanks.

Thanks for the advise. Can you have any other fish in the same tank with an angel? Or is it going to be just that one fish in the tank?
