Ok, here is my plan I am going to be getting a DSA 215g tank, its 72x24x29 and I was daydreaming about the stock list. I was debateing weather i could put an Atlantic FW ray in there. They are they only Legal FW ray for aquaria in TX. But I seem to be having difficulty finding info about them as it pretains to keeping them in aquariums. How big do they get overall? will this size tank be large enuff and would it be compatable with maybe a couple oscars or dats and a Jardini aro? Or would It have to be a species tank?
