Atractosteus tropicus is insensitive to most water conditions, provided they are kept in a warm, tropical climate. One does not have to have much aeration as they are air breathers. A moderate pH is recommended, though others (whether notably low or high) can be tolerated. Most gars are very resilient to water conditions (with the exception of the pH sensitive Cuban gar) but clean water is still important for your fish’s health and longevity, so remember to keep up on water changes and have abundant filtration to deal with the excessive waste left over by these large predators.
Need to note on the above that all Atractosteus gars are very sensitive to quickly fluctuating water parameters. It is not just the Cuban but the whole genus. Tropical gar thrive in static conditions and quick change in Temp, pH, hardness, Ammonia, Nitrite level can be hazardous to their health. In general Atractosteus gars are resilient but they do not appreciate quick changes in anything.
