Water Quality

Below is a guide to what your general water quality parameters should be. Aquariums with poor water quality will cause inhabitants to become more prone to disease. Environmental Parameters Fish Only Systems - temperature 24°C to 27°C
- salinity 1.022 to 1.026, whatever your salinity in this range, being constant is most important
- pH 8.3
- ammonia 0 ppm, may increase during feeding, but should drop to 0 ppm within 2-3 hours
- nitrite 0 ppm, may increase during feeding, but should drop to 0 ppm within 2-3 hours
- nitrate up to about 50 ppm, but have seen healthy live stock in a well stocked system of 150 ppm (included Tangs, Butterflies and Angels, but I would not recommend it)

Water Quality

 It would be true to say that the majority of aquarists never test for dissolved oxygen (0 2). Nevertheless, oxygen is an extremely important gas and essential for the survival of the vast majority of livestock that we keep. This is, of course, most evident in fish, which draw oxygenated water in through their mouths, passing it over oxygen extracting membranes within the gills and expelling the depleted water out through the gill slits. |

Foods and Feeding

 If you've never been eaten out of house and home by a few fishes before - be prepared - as these little guys will do just that. They are greedy and will never miss a meal when offered. Most Malawi Cichlids are good feeders - so starvation with these creatures is rarely an issue - unless being continuously bullied into hiding. |

Marine Foods and Feeding

-
Frozen Foods - cockle - feed to bigger fishes unless you chop it up,
- mussel - a bit messy, but smaller fishes will eat the scraps,
- gamma fish - whole fish for the larger inhabitant,
- shrimp
- brineshrimp - not very nutritious, however often a good food to wean picky feeders,
- mysis shrimp - more nutritious than brine, but the exoskeleton can be too hard for smaller fishes,
- gamma shrimp - similar size to the mysis shrimp, but with a much softer exoskeleton - a tasty treat,
- clam - some fishes need to acquire a taste for it.

Marine Fish Diseases
|
|
Common Causes Of Disease The cause of most disease in marine fishes and invertebrates is simply poor environmental factors i.e. poor water quality. On the whole marine fishes are extremely disease resistant, but when things go wrong in a marine system livestock can deteriorate rapidly. |
