Congratulations on your step into the marine world. Three kinds of clowns in a 37 gallon, that is pretty risky setup, ie very possibly a stocking problem in itself. Maybe you already know this, but clowns are territorial & get more aggressive as they get older. They don't like hands in their tank at times, another clown is worse
. I wouldn't recommend mixing two kinds of clowns unless it was a tank over 100 g. It may may work out fine (and does for some for a while), but it is likely to be war later on.
Are you using water from someone else's tank/another tank of your own? You might want to slow down. I add fish at a rate of every month or so, it is essential to let the biological capasity of the filter to keep up. I let my tank set up for a good long time (over a month) using water from another tank, would wait longer otherwise. It would be good to read about the nitrogen cycle of the tank, etc at this point.
I'd recommend waiting a bit to see how two fish go, patience is the biggest key to this hobby. I kept one fish (after cycling) alone for a while & Fred is still in my tank years later. The key to a happy fish tank is to have non-stressed fish. If you keep them happy and give them everything they need, life is good. Feel free to email me or private msg me, if you need something particular, I can offer some good reading materials if you have questions on certain things.
Oh, make sure that you have a test kit, something to test salinity, etc etc.
