Would this be suitable for a 10 gallon tank?

That's a few too many fish.

Take out the zebra danios as they are a bit big and active for a 10gal anyway.

Then it's possible. The Otos can be a bit delicate and tricky to feed. Make sure the tank is well established and has some algae for them to graze on before you add them. I wouldn't try putting them in a tank less then about 3 months old.

Good on you for asking first. There are lots of different opinions on what will fit in a tank, but one thing that's always true. If you put less fish in, it will be easier to look after, and you will have less problems. You don't see people signing in here and asking why their fish are dying because they have too much space do you?

That's too many you can remove all the zebra danios and 1 neon tetra. But if your really want to have them all you can have 15 Gallon Tank for all of them.

No zebra danios and 1 betta might be fine.

it's too many fish for a 10 gallon. sorry. I mean, it's your tank and you can do what you want, but a 10 gallon is simply too small for all those fish.

no, take out the zebra danios and it would be okay

Thats a little too much, don't get a betta. Leave room for vegetation.
