You're going to be overstocked with that mix. A dwarf lion can get to 5-6 inches, that and the clowns are going to put you right on the limit, that's if you get rid of the current inhabitants.
Most people reccommend anenomes for an established tank. I can tell you that I put in two anenomes in about the same time frame as you have and my water quality went way down. Most people agree that anenomes need an established tank.
Even though your cycle is complete, it's not necessarily time to add fish. Your H2O readings are "good" but that doesn't mean the tank is stable. Let it sit for a while (at least 2-3 weeks) to let the bacteria colony stabilize and establish itself. The problem is, if you add new fish, you're going to start a mini-cycle all over again.
I'm speaking from experience, because I added things too quickly and lost everything to an ich outbreak. I had to let the tank sit for 21 days and over the past 6 weeks have added two firefish and a lawnmower blenny.
Each time you add a fish, it's waste places demands on the bioload. If the tank is established, the environment will quickly adapt to the additional waste from the fish. But if you add too quickly, it's harder for the tank to adapt. Think of your cycle as a rubberband. During the ammonia spike and nitrate/trite processing, the rubber band is continually stretching until it reaches it's limit and the environment is quite unhospitable for fish. Once you complete the cycle, the rubberband stops stretching and the stress stops building. That's exactly where you are now. Let the tank stabilize and mature a bit more.
Also, Lions and eels are very messy eaters and give off a lot of waste. The food they don't eat or the scraps they leave behding plus the comparative amount of waste they produce creates alot of ammonia in the environment. If your tank just went through it's cycle, it may be hard to accomodate these types of eaters right away.
Again, I speak from experience. I had two beautiful lions and their skin just peeled off, rays were sticking out and I lost them. It's tough to wait right now. But if you're not careful, you will have to wait anyway and you'll have to deal with the heartbreak of losing fish.
Be patient, enjoy the sights of what you have now, carefully select your inhabitants and move slowly. That's the way you can get the maximum enjoyment from the seascape you eventually create.
Good Luck!
