The African Rift Valley Lakes are freshwater; they are not brackish water. They all drain via rivers which are also freshwater (obviously). Example, Lake Tanganika, the largest and most alkaline of the rift valley lakes and the second deepest lake on the planet, is part of the Congo River basin and supplies the water to the Congo River via the Lukuga River. The Congo River is not brackish, it is absolutely completely freshwater containing no sodium salt.

There is a vast difference between "salt" as in brackish and sea water, and the "salts" that provide the alkalinity to the freshwater rift lakes.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Dragon gobies are very peaceful fish despite their look. They are shy and like moving food. I had one in a tank with tetras and mollies and they out-competed it for food. I was very upset when it started to freak out (swimming rapidly up and down the tank walls) and then died within an hour (water parms were normal). I had never seen it eat, as I had read it was a nocturnal feeder, so I dropped sinking pellets in after I fed flakes to the other fish and turned the lights off. This fish does better in its own tank with a fine sand substrate and caves, as it likes to dig and hide.

Hello, on the subject of dragon goby's and cichlids: in my experience it depends on the size of the goby and cichlids. If the goby is large enough the cichlids should leave it alone. On the subject of brackish or fresh water both are usually sold as fresh water fish and bread that way and will thrive and do well in a fresh water tank. If you already have a brackish tank and you want to introduce one of these breeds do it very slowly, even though a fish may live in brackish water in the wild if it was captive bread in fresh that's where it usually dose better.

Aj, this thread is from 2009 it is best that we don't respond to old threads but rather create new threads. As far as gobies and other brackish fish being bred in freshwater - it is highly unlikely and they do need brackish tanks, regardless of being sold in freshwater.
