Suitable predators for a nano

[Shon]

I'd consider this a predator. It's also a small size fish that will work in a nano. Only issue is they're good at hiding, wedging into spaces and they also camouflage very well against anything white, grey, tan or black.

I consider it a predator because it eats fish roughly it's own size. A scooter got to close to his hidey hole and was gone in an instant.

no predator fish in a 10 gallon.

I would think a red waspish would be fine. Mine barely moves around at all

30 gallon and you can do toby puffers, dwarf lionfish.

Would not put a dwarf lion in a 30, they grow so fast

I agree with Lion King. I wouldn't recommend ANY predator for a 10g. Sorry.

100%

Hermit crabs are pretty predatory.

Perhaps a coral croucher? They’re tiny scorpaeniforms that are mildly venomous and predate even tinier invertebrates. They tend to hide a lot so you might have difficulty getting food to them though.

Hermit crabs are pretty predatory.

Second that!

Your tank is a bit small for predatory fish like mentioned already. I would double or triple the tank size.
And if I were going to try a predatory fish, it would be some kind of angler. They'll sit there all day waving their little lure around until something gets too close and then WHAM. They're pretty cool. Ugly SOBs but some find that cool too.

I appreciate all the responses and advice! It’s really appreciated and great to know. I’ll steer away from anything mentioned until I have the space to get a larger tank. Thanks a bunch!!
