so you are going to put rays in a 65 gallon tank 36"x16" bad idea ,with retics they are so sensitive and 65 gallons is not big enough.unless you will be doing water changes twice a week 50% each time.
In fact my first ray i ever bought i put in my 36"x16" and killed it.You will be doing water changes twice a week if you plan on feeding this ray shrimp.You can get a ray to survive in that tank but dont put retic in it.They will die very quickly when amonia and nitrite levels go up even just the slightest bit.
