I have two large tanks,One will have arowanas{Silver and blacks) and rays the other has arowanas(silver and blacks) and huge polys. Will clown loaches work with rays or polys or neither along with the arowanas??
CL's should work with all of them provided you get ones that are large enough to not be eaten when the others are fully grown due to their slow growth rate, but you probably knw that alread
cls need decor and putting decor in a tank with rays would give me thing to be concerned about and polys will try to bite the bottom dwellers my 5" sens had mauled my 3.5" dojo loaches
