Update : 63 wigglers.
Thanks Jeep and fishmama.
I have them in about 65 % RO water right now. They spawned about four times in a 125 gallon tank with 9 other discus their size and age in just aged tap water. Out of these four spawns not one wiggler so I moved them to their own 30 gallon and dropped the temp a few degrees and really softened their water. Fed them alot of frozen blood worms and Tetra bits and waited a whole 2 days before they spawned again. Right before they spawned I did a 80 % water change with about 75 % RO. That dropped the TDS down to around 80. I am going to start adding some hardness over the next couple of days.
I really didn't expect any wigglers since the MP is pretty young.
Thanks for looking.
