SIZE OF SUBSTRATE: Substrates vary widely in terms of size - everything from sands consisting of very tiny particles to larger river rocks. Large particle substrates allow more uneaten food and waste to penetrate into it leading to toxic build ups if not cleaned. Small particle substrates can compact which may lead to areas that lack oxygen. These areas can eventually release hydrogen sulfide - a substance that is extremely toxic to fish. The size of the particles also has a big impact on the health of the fish and the ease of cleaning. For instance, some fish like to scoop the substrate in their mouth and move it around. It is not a good idea to mix these species with sand because the small particles can irritate them. Sand can also be somewhat difficult to clean as the small particles often get vacuumed out of the tank along with the waste. On the other hand, some fish enjoy making nests or homes out of the substrate and in these instances, large particle sizes would not be conducive to this habit. As you can see, it is important to research the specific needs of your fish when considering the appropriate particle size.
