These fish were selected because they all do well with seahorses. They are all non-aggressive, reef-safe fish that shouldn't be interested in your seahorses. They can be kept in the same water parameters and will eat the same food. Please note that they will compete for food with your seahorses. Be sure to feed enough so that your seahorses aren’t out-competed. No additional care is needed for any of these species other than additional feeding. Remember the more fish you have in your system, the more waste is produced, and maintenance practices should be increased to accommodate. KEEP YOUR NITRATES UNDER 20ppm!
