Jessica V asked:
My parents have a hexagon shaped tank in their house and they stock it with fish that never seem to live as long as they should. I would like my parent’s tank to be the best that it can be for the shape that it is and when I learn knew things I pass on the information to them. I’ve been interested in the art of fish keeping and aqua gardening for about a year now and I’ve learned a great deal since I first started the hobby. I was thinking about the aquarium at my parents house and I wonder what species of fish would thrive best in a hexagon shaped aquarium because I know its a very unnatural shape for the aquarium environment. Do you know of any fish that wouldn’t mind living in a tall hexagon aquarium? Please also tell me if you have any of these fish, how old they are, and if they’ve grown since you first got them.
I have a 55 gallon (rectangle shaped) aquarium with 4 fan-tailed goldfish and a 10 gallon (rectangle shaped) tank with 5 white skirt tetras. I bought the tetras because I wanted to support buying unpainted fish.

All fish are better in a more circular aquarium, they just need the right care and handling?
Fish that don’t make a lot of lateral movement are best. Fish like Angelfish, Discus, Guppies, Gouramis, and slow moving Tetras are good options (DEPENDING on the size of the tank). Avoid fish like Danios, Loaches, Hatchetfish, and other hyper fish. Email me if you have any questions and please post your tank size.

EDIT: Goldfish are coldwater fish, and should really be kept by themselves. They should do well in a tall tank, but a rectangular tank is still best because it provides maximum surface area. If you got rid of the Goldfish, you could do the tropicals I listed earlier, but DO NOT keep them together. In the 10 gallon (I applaud you for supporting non-painted fish), you might want to add some Cory Cats or Otos. They are fun little fish that are constantly on the move. As always, feel free to email me.
I always liked having a school of neon tetras. They are small (but colorful and popular) so I didn’t keep any agressive fish at the same time. They start off really small but get to about an inch long. I also liked a couple of sucker fish and spotted sucker catfish.
I also kept a few black tetras:
When I got tired of it, or they started dying off, I put a couple of Jack Dempseys or Oscars in there. They get pretty big and are fighting fish. I think that you need more than a ten gallon aquarium.
I had angels in a hex tank.they did very well.Two of them laid eggs ,though they never hatched.
The ever popular Beta does well in tall tanks, too.
