I probably used more ammonia than necessary but I wanted to make sure that my filters could handle whatever bioload I added. Originally my goal was to add all the fish pretty much at the same time, but I ended up splitting that up, which was fine. And I had zero spikes no matter what I've added so far, so obviously something worked.
As far as the mystery mollies go, I really don't know. I would start a thread on it and post pics if possible. Odds are they are either a hybrid with perhaps platies or just a different mutation of molly color. I know the pet store had some "cremesicle" mollies, which were an orange and white color. Very pretty, and I would have picked up one or two females, but they all looked really unhealthy so I skipped them. I may keep my eyes peeled for one in the future to add to the tank, but we'll see.
The julii cories arrived today as scheduled and after a good drip acclimation, I added them to the tank. All seems well and I will try to post some pics this weekend.
The sev should be in next Wednesday, and at that point I am going to consider the tank fully stocked, at least for now. We'll see how it goes, but at this point I'm comfortable with the amount of fish and not really interested in pushing the limits.
