How large should my tankmates be to be safe from my sen or ABK? I was planning on doing a "nice" SA tank with my sevs, juruparis etc, but I'm thinking I'll go ahead and add my sen and ABK to the mix. I'd assume that eliminates any large tetra shoals or cory shoals, but how big will my other fish need to be? I've had the sen for 9 months and he doesn't seem to be growing (he's maybe 7").
