Sorry to say the clowns will grow too big for a 30G tank.

What kind of catfish do you have? Some stay quite small so should be fine, depends what kind it is.

Likewise with your 'sucker' depends what kind it is.

Also Tiger Barbs can be very very aggressive.

This number is a little conservative, but it is a good place to start. I have read that for every one inch of fish you should have one gallon of water. I believe that shoaling fishes give a little leeway on that.

P.S. As far as inches of fish go, that is the expected full grown size, not size at introduction to the tank.

General rule is 1 inch of fish per gallon of water or FREQUENT water changes-especially in a small tank like a 30 gallon.

The tigers are too aggressive for the mollies. I'd watch out for nipped fins-or worse. Our tiger barbs chopped three otocinclus in half within 12 hours. Keep them with other aggressive fish like other barbs, red tail/rainbow sharks, armored catfish (like a spotted Raphael).

Also, be careful with your "sucker". Most plecostomus are small when purchased, but can grow to 12-18 inches.

Hopefully it's a good dwarf type, like clown, rubberlip, siamese, otocinclus, etc.

Watch out for chinese algae eaters. They don't eat algae when they get larger, but go after other non-aggressive fish (mollies?).
