Scats - Anyone Keep Them?

Must have pollutant-clean water but, turbid. Scats prefer green water and increasing saline levels as they mature. Eventually becoming heavy brackish/low marine salt levels. I was able to achieve the greenwater without a constantly clogging filter by utilizing a pond filter with coarse bio-materials.
Any plantings you attempt will become the next meal on their menu.
They're not schooling fish as adults but they will loosely shoal. Aggression is curbed by keeping either 1 or many. Trying to maintain 2 or 3 will result in battering from the dominant leader. This is one of the "fabulous 5" species where the number to maintain is 5 or above.
They possess rasping teeth for making short work of hair and other macro algaes. Captive feedings can include raw cabbage, turnip greens, brussel sprouts, frozen peas, and just about any fruit. The occassional meaty food will do them good and may include; bloodworms, brineshrimp, mysis shrimp, etc. Prepared foods such as algae wafers, veggie sticks, rabbit pellets, and frozen marine herbivorous diets are also readily taken.
Because of their large adult size, shoaling numbers, and water parameter requirements, scats should be housed in as large a tank as possible. I had a dozen foot-long silvers in a 300gal and it looked overcrowded and needed frequent water changes due to their amount of waste (like active placos) and messy eating habits (tearing and rasping).

BTW, there is a species of scat (Scatophagus tetracanthus - striped scat) that doesn't inhabit marine environments. They hail from the Pangani River in Tanzania. These fish can be maintained under the same conditions as rift lake cichlids (high pH).
Their downside is that they have a frustratingly rare availability. And, when a precious few do become available, they usually carry a very high price tag.
