I'll look for some, so far my research says stream type tank with uni directional flow with a slope Clear water with a lot of vegetation. So, my idea is Vals on one side, heavily planted. The aponogeton in center back, dwarf grass in the middle carpet, and ferns on the shallower end. So they have the Vals to hide in and the middle and ends to swim in. What would be a good spawning medium for egg survival. Also would cherry shrimp be a good cleanup crew that won't go after the eggs? I'll try to prevent snails from getting into this tank.
