Fish compatibility is a very important decision that needs to be made anytime you wish to add a new member to your aquarium. Fish that are enclosed in a small space with a species that is not compatible will lead to fights and squabbles that could lead to death or stress. Stress is a sure fire way to allow ‘Ick’ to creep into effect and spread to every member in your aquarium!
Aggressiveness also needs to be considered. While your aquarium is cycling it is a great time to plan your stocking wish list. You should always stock using your least aggressive fish first and your most aggressive fish last.
Always research any new fish before buying so you can provide the best habitat for that fish to thrive. Use the chart below to help you with your planning.
