Marine Compatibility Charts

There are many factors that determine whether two animals can live in the same tank. Marine compatibility charts can help you choose wisely.

All fish, corals, and invertebrates have their own unique personalities which affect how compatible they are with others. Other factors that may affect how animals will react to new tank mates include how well-established your tank is, the availability of hiding places, how much room they have to swim in, and the order in which your current inhabitants were added to the tank.

Coral Care Guide

The keys to maintaining healthy corals over the long term are stability, knowledge, and patience. You should not add corals to a new tank for at least a few months because there can be dramatic swings of ammonia, nitrite, and pH. Take the time to research a coral before you purchase it and add it to your tank. Important elements to consider include its compatibility with other livestock, it’s temperature, flow and lighting requirements, it’s feeding needs, and it’s sensitivity to water parameters including salinity, calcium, magnesium and alkalinity.

Anemone Compatibility Chart

With help from the marine aquarium community, put together a helpful marine compatibility chart on anemones (see below.) The chart includes important information such as which anemones can be kept and even be close enough to touch in an aquarium and which anemones can NOT touch each other (and should probably not even be in the same tank together.)
