Aqueon Column Tank stocking advice

[almac]

Hello,

I have had my Aqueon Column tank for a while now and ran a fishless cycle for a month. All levels were achieved. I then started off with 4 Harlequin Rasboras. A few weeks later I added 3 more. A few weeks after that I added 3 German Show Guppies and 1 Trapdoor snail.

Everything seems to be going well! I was wondering if I could add one last fish or snail and, if so, if any of your had any suggestions. I would be willing to upgrade my filter if need be.

Specifics:
Column Tank (15.25" x 15.25" x 18" (accounting for gravel)
Aqueon QuietFlow 10
Heater

Thanks in advance!

That is about 18 gallons, so you could definitely add some more fish/snail but it depends on what fish you want.

 

[Fishperson]

You could add some more guppies. Not too many more fish though.

Thanks for the responses so far. Anyone else? Something orange or red?

Dwarf gourami would be okay

Great idea! I would add a flame dwarf gourami, they are orange and blue, really beautiful. You might be able to add more guppies, but remember that they are really messy fish.

I was just wondering since he has an 18 gallon tank, if he's kind of under filtered with just the Aqueon 10 on there?
