Question on if this stock would be OK. Jaguar pair in an 8 foot 180 gallon (96 x 18 x 24). Substrate would be PFS with large pieces of drift wood. Filtration would be 2 FX5's. Would have a decent size school of silver dollar / red hooks for dithers. When trying to get a pair is it best to buy 4 - 6 and see what actually pairs off or try to already find an established pair? Have the tank and one FX5 so far, still have to find another FX5 and build the actual stand, heaters and so forth.
