Considering the results it really doesn't surprise me that we haven't heard much else about natural breeding for dats. Even using 5 cement ponds with 6-11 fish each, after 8 months the only results are 230 baby fish that survived. Considering that this is an egg laying species those are very poor results. When you think about the costs of maintaining those sorts of setups long term, and compare it to the relative ease of catching wild fish. Think about all the mini tigers that showed up a couple months ago and the numbers they showed up in. What is the incentive for trying to captive breed indos.
