I concur, motion passes.
Fishing-proof your tank. Usually something like a mosquito net is great but making sure all holes are plugged will keep fish in AND cat out.
I would assume that if fish HAD jumped out your cat would invoke the "my second rule" and had treat with him.
Cheap clear plastic lids that precisely fit around heater wire, filter and air hosing can be made by just about anybody. Most large hardware stores sell stock sheets of acrylic "plexiglass" and these can be hand sawn slowly with hack saw blades or jewelers saws. The hack saw blade is usually the better option. You can cut it to fit larger than the top of your tank or to fit inside the top and it will still cost less to make than a hood costs to buy. You cut V's for hoses and wires and you can nibble away curves in thin sheets using toenail cutters. Your dad/mom might know how to handle it as well.
A couple wooden slats from back to front to hold the light up.
I lost three fish to a cat and another fish to attacking the cat. My only true-green female VT was knocking other girls away from the cat paw and got badly infected. The cat was dealt with decisively by a high voltage supply designed for such purposes. Empty water bottles with bells inside also work as discouragements because kitty can't stand them back up.
