5 Gallons is the Minimum for Cycling. Any lower it would be too hard.
You don't have to Cycle, but you need more Water Changes than usual.
And for the Hood, search on Amazon. They have a lot of things.
But, I have this 3.5 Gallon Tank that you could search up. It's called " Top Fin 180 Aquascene". Something like that. It comes with a Filter, I put mine in Storage, and LED Lights. The Tank of course. It's a Perfect Fit in my kitchen. But remember, Bigger is Better!!! Get the Biggest Tank you can Afford.
