What are there water temp ...ect requirements and will they adjust ???
I am planning on setting up a 20ft long x 8 wide x 4 tall custom fiberglass pond with its own stand alone filter system.
Any help or advice would be nice btw this is on top of what I all ready am setting up for the rest of the rays I currently and having a 5000 sq ft indoor hatchery built from the ground up.
I keep TIgers like most Amazon basin rays - upper 70s to low 80s for temp, lower pH. Lots of variation in lighting over the tank's foot print... give 'em light and dark areas, and areas of higher and lower flow.
