15 Gallon Column Tank stocking

[AshleyD]

Hello! I have a 15 gallon column tank with 8 Glo Tetras in it and nothing else. Is this an ok size for them? It’s a little awkward to scape without overcrowding.

A 15g tank is suitable for a small group of black skirt tetras. A tall tank isnt as good as a more traditional 15g tank as it will have less surface area for oxygenation. So you should make sure you have plenty of surface agitation (either from your filter or a bubbler) to oxygenate the water, and good circulation to get that oxygen throughout the tank.

Are you seeing any issues with your fish?

There was some bullying towards the smallest Tetra at first but they all seem to be ok right now. I do have a bubbler but may upgrade their tank in the near future to a 20 long
