So, being that these two species seem to be able to tolerate a small group of themselves I have decided to se up and heavily planted 75g tank. Driftwood and plenty of plants will be used to break up line of site and provide territory. Only other tank mates are my upside down cat who is peaceful but big enough to be safe, and my soldier armored cat who is never seen and, well, armored. The SAPs look awesome, and seem more peaceful, however the teeth trimming scares me. Salivators are awesome as well, so I'm kind of tied between the two. I should be able to keep around 5 or 6 of each. Tank will be extremely over filtered. Any tips or recommendations or opinions on these two species and my idea? Also, anyone know where I can find either for sale? Having a heck of a time.
