Fish Tank Planner is an online application designed to help aquarists have healthy and successful fish tanks. The purpose of this application is to avoid common mistakes and pitfalls when planning which fish to keep in your aquarium. Some of the things that fish tank planner can help you with are as follows:

  • Fish compatibility
    • Aggression: Generally aggressive fish can only be kept with other aggressive fish.
    • Gulp: The ability of a fish to eat smaller fishes.
    • Water: Fish Tank Planner will tell you the ideal water parameters for your tank.
    • Behaviors: Some fish are incompatible due to behavioral issues.
  • Fish quantities
    • Number of fish per gallon: Calculates the size of tank needed for tank
    • Number of fish per bottom area: Calculates the bottom area needed for tank.



What if a fish species that I am looking to add does not exist in the database?

We are still in the beta test phase and we are adding fish to the database daily. Once we are done adding all of the fish we have planned, we will begin adding user requested species. To request a species, please send us an email via our contact page.
