Ray tank? What do I need?
At least 3-400 gallons for the smallest rays. The more room the better. Honestly would not recommend starting saltwater with a stingray tank. You’ll need a good skimmer, power heads, tank, sand, rock, they will need different food varieties(shrimp, silversides, other meaty foods).
20 Gallon SPS reef
29 Gallon FW "fat catfish" tank
