Okay thanks for the Id
I have well established 30 gallon long tank planted with driftwood and moss my fishes are rummy nose tetra,endlers, platy and some sort of shrimp I keep my water at 27c and my water is hard is my setup okay for them or not?
Is this true that they are brackish fish??
Some species are brackish, but the common Halfbeak (which is what yours appear to be) is a freshwater species. Your tank sounds fine for them, they will stay at or near the surface most of the time, and I don't foresee any conflicts with those species.
