So my CA/SA has evolved and I'm contemplating thinning my tank down to 1 pair of festae and 1 pair of chanchos. Its an 8'x32-33" wide by 24" deep tank. What do you think the odds of co-existing are? Or should I stick to the original plan of an all male tank and hang onto a few other amphs that I have as well? Or maybe do the pair of festae and then keep a male chancho, rd, amarillo, and midas?
