What corys for 75 gal community tank?

[Decidueye_]

I recently set up a fully cycled 75 gallon tank with 10 serpae tetras 10 black phantom tetras 3 pearl gouramis and a pair of koi angels. I want something bottom dwelling to really complete the tank but idk what. My first thought was corys but I want something large colorful and affordable. I'm also open to non cory bottom dweller suggestions.

pandas are fun. there's also peppered, sterbai, elegant corys, aeneus corys, albino aeneus. skunk corys. and those are just a couple of the cheaper ones. you can get vulcan cories for several hundred dollars a fish. but it's all personal choice. I have pandas and skunks. for a 75g, i would get a large group of one type. you don't want them interbreeding. I have 12 of the skunks. they go all over the place in this size group  

you could also do a bristlenose pleco with the corys. either super red or albino would give you more interest at the bottom

If you want something large, a brochis or scleromystax species could be fun. Most species are also very colorful, especially S. barbatus.
