Hoplosternum punctatum are in the Callichthyidae family like the corydoras are, but bigger. Just as dopey and peaceful. But the hoplosternum punctatum species should be kept 3 or more, 40gal being minimal for a trio. Very active, grow to about 3-4 inches. Mine are all over the place.
Downside is they share the same common name "spotted hoplo" as their larger cousin, megalechis thoracata, and are much less common. But if you can find them, theyre fantastic options. And last downside... they may dig up some more delicate stem plants like carpet plants, but sturdy rooted plants will be fine.
Mine are goofballs.
