Almost everything you have are schooling fish, I'd up your numbers to at least five of each. What m/f ratio do you have for the guppies? Dojo loaches are subtropical and shouldn't be kept above 70f, not sure how that will work your other fish

I say that it's a Japanese loach but all the store said it was just a loach. It was with other tropical fish. 4 male guppies. No female. If I up everything to five would there be room for any additional different types?

Everything Ifind on google for Japanese loach is showing dogo, so you may have to look it up to be sure. As to stocking, adding all that should be ok (do it in small batches) but adding anything else depends on what you'd want to add :/

You were right about the Japanese loach. I have a Japanese weatherfish. As for variety, I guess something that has color and will stand out. I was thinking angel fish but I wasn't sure if they would work
