Have 6 harlequin rasboras and 10 neon tetras in a heavily planted 40b. Only other inhabitants are two danios, 3 otos and few shrimp/snails.

The rasboras do not shoal and chase each other around. They also sometimes harass the neon tetras who now stay primarily in the front corner of the tank. Anything I can do to change this behavior?

I've got 8 rasboras and 1 gourami in a planted 15 gallon. The rasboras seem really happy, they are a bright red color and some of the fish I think are trying to breed. One will swim upside down under a leaf and flap it's fins real fast, I'm guessing that's breeding behavior. But mine rarely ever shoal. They do chase each other around though. Before I planted my tank I had some fake plans and decorations, really ugly but that's beside the point. They would all stick to a group in the corner and never come out. Once I planted it they come out and play around and have changed color to reddish and they're just much happier. So basically, it seems like everything is right, you have a lot of plants. My experience is that they like swords and crypts and things they can swim between and feel sheltered by. So if your tank is full of furcata for example, you may want to thin it out so they can swim between the plants

also you may want to consider adding a few more raspboras, 6 is the bare minimum so they might not feel too safe

Chasing is classic behavior in shoaling fish such as rasboras, but it will not harm any of the fish involved as long as there are at least 8 to 10 fishing the school. By the way, you might want to up the number of danios for the same reason, as even if they are not harassing other fish they may be nervous and short lived in such small numbers.

Yeah, the rasboras seem fine but I'm more concerned about the tetras being chased and staying in front corner of tank. Not swimming about. They feed just fine though

Ah well the only thing I can think of is to add more tetras so they have a bigger school, my rasboras are big and could probably eat a tetra.

Alot of times you'll find that schools work better in odd numbers.

Certain rasboras are territorial because they lay their eggs in isolated locations, i.e. not egg scatterers. Thus, they chase away other fish to establish a territory for potential breeding. Eggs scatterers typically don't exhibit this behavior since there is no need to establish real estate for the deed.
