Aquarium condition requirements for your Large Catfish

Minimum aquarium size - depends on species of Large Catfish. Small Otocinclus are fine in an 18” x 10” x 10” (46 cms x 26 cms x 26 cms) but are usually kept in a community tank to perform their algae-clearing duties. Others may need much more space - so do research the particular type you want before buying.

Temperature - generally will tolerate a wide temperature range from 65oF to 80oF (20 to 26oC).

Water parameters - although many of these Large Catfish are found in soft water, they readily adapt to hard water.

Habitat - many of these Large Catfish, can only be kept in tanks with a rock-work décor. On the other hand, others are fine in a planted community tank. Plants: some of the larger Large Catfish, will undoubtedly cause havoc in a planted tank. Research is necessary.

Large Catfish behaviour with other fish

Many Large Catfish become very sizeable. Adequate research is recommended. Some can be cannibalistic towards tank-mates.

Large Catfish diet

Some are algae eaters, others will happily dine on frozen foods or, as in the case of some of the larger Large Catfish, frozen fish. Fish with large appetites equate to large amounts of waste: an efficient filtration should be used.

Large Catfish health

These fish are not particularly prone to health problems.

Habitat - freshwater tropical fish

Sociability - important to research the particular type you want
