hey i was wondering if rays need a certain tank height...i found a pond online its 8ftX4x1ft i was thinking of trying to breed rays but is that tank to little of height
It sound like a very nice tank. Consider replicating a back water area with root s, stained water neons and a small motoro or two. Small meaning 4-8 inches.
If you want larger rays in it you may need to apply some sort of do-it-yourself rim. Rays get frisky and sometimes test the limits of their tanks accidently.
By "back-water" I am referring to the sloughs; slow moving dense structure areas where juvenile fish are found mostly safe from predators.
Some neons, plecs, corys, hatchets and a small motoro or three.
Just my humble opinion.
