Rhino Gobies and Panda Tetras?

[sadness child]

So I got 10 panda tetras not knowing that they were aggressive. So when I put them in my 46 gallon tank their aggressive nature pushed all the other fish into hiding. Other than the cories and mollies. So I moved them into a new 20 tall tank alone.
In the bigger tank there are 4 Rhino Gobies that are about 1.5-2 inches, that are not seen to often. The thing is though, that I have a good 16 or 20 2-3 inch cories in the big tank. And to me that feels as though there are too many bottom feeders.
I did not notice the panda tetras doing anything to the gobies, and there are a lot of hiding places and place to perch for the gobies in the 20 gallon. But I am still unsure if I should put the gobies in the same tank or not. Or if I should try other fish.
On a side note, I would like to add 3 honey gouramis, but that I don’t know about either. Any help is very much appreciated.

When you say Panda tetra, do you mean Aphyocharax paraguayensis?
Because they are reasonably peaceful and shouldn't cause problems to other fish.

Most gobies come from salt or brackish water. The tetras come from soft acid water without salt. Do you have a scientific name for the rhino gobies?
