Aggressive ruby shark, what should I do?

I’ve got a ruby shark in my tank and it’s becoming really aggressive towards the other fish (it was fine for the first three months). It keeps chasing them around, guarding certain areas of the tank (the boat the ruby shark wont let anyone in), and generally stressing everything out.

Has anyone dealt with this before? Is this normal ruby shark behaviour, or is there something I should change in the tank setup?

Hey everyone,

I’ve got my aquarium to a really solid place, water levels are spot on, the fish are healthy and active, and all the plants are real (which I’m pretty proud of).

It looks great to me, but I’m wondering if I’m thinking too much from a human perspective rather than the fish’s.

From a more natural / fish-first point of view:

  1. Is there anything I should consider adding to improve their environment?

  2. Things like driftwood, rocks, hiding spots, or even leaf litter?

Would adding more fish actually benefit the ecosystem, or risk upsetting the balance I’ve got?

I’m not trying to fix something that isn’t broken, just want to make sure I’m giving them the best, most natural setup possible.
