Your Moor should do fine in that temp. of water, mine do fine in water in that range. A 20 gallon planted tank sounds like a fine home for him. Not much to tell you about black moors they are pretty much the same as most fancy goldfish only have odd eyes and are black, but there color can change my moor has gone from nice black to a orange. They get to be about 6-8 inches long, as for jumping im not sure.. why do you ask? do you have a cover on your tank? mine has never attempted a jump but a few of my fantails will occasionly try it. I find a good food to feed is sinking pellets because they dont swallow air like they do when they eat something off the surface, this can cause swimbladder problems which are not nice. Also be sure to soak any food you feed them so that it obsorabs water before they eat it insead of in their stomach. Also i believe he should be fine in with your tropical fish, i had to put a gamori and some neon tetras in my goldy tank and they seam fine. anyway i hope i was of some help. Niki
