Ok so to make a long story short, my tank was 90% stocked. But I lost a few inverts And recently lost a guppy to a filter :/ he swam behind it and got trapped poor thing.
So I've been on AqAdvisor and I'm now only 83% stocked.
I did a few options and I can have another guppy
+ 5 neon tetras (only small fish I could think of at the time)
But the thing is I already have a school of 6 neons. So I wanted a different tetra, or other small fish to do another school. (Not glow lights) I have herlequins and the colour isn't that different.
I opted for harlequins because I wanted a contrast in body shape as well as colour.
So the question?
What other small schooling fish could I use to add colour/movement?
Current fish colours are: red/orange/blue/black/gold/yellow.
Edit:: I'd doesn't have to be a schooling fish as long as it has the equivalent bioload :p.
