Can Corydoras Or Kuhli Loaches Ruin My Substrate Design?
So I'm nearing the end of my cycle and am starting to think about my stocking options and I'm considering keeping 6 Panda Corydoras or possibly even Kuhl Loaches among other fish in my 125L (33 Gal) Tank (81cmx50cmx36cm).
As you can see, my tank is mid-heavily planted, but more importantly, I have designed my substrate such that there is a bed of white sand acting as a, admittedly dirty, "river" separating my main substrate (ADA Amazonia II).
My question is this: Will the digging nature of Corydoras or Kuhli Loaches ruin my substrate design? The ADA Amazonia Aquasoil is incredibly loose and even a little bit of digging can create a mess.
I'd really appreciate some insight on this guys, thanks!
