Hey Sandeep,
well a brakish water environment is a very versatile environment because the water chemistry keeps varying from time to time.
Unfortunately, it is one aspect which is mostly neglected by aquarists - even on most aquarium related sites there is generally no specific section on the brakish water aquarium.
I just yesterday visited my brother in law's shrimp farms and was able to see and make notes of some fish and aquatic life that normally comes into his reservoir ponds from the creek and there are a lot of fish and inverts which normally were never supposed to be there but still survive the brakish water environment - just to name some - I could find there mudskippers in abundance along with fiddler crabs, silver sides, wild shrimps, sea bass, some gobys, even a wrasse (still not positively identified by us), some eels, mud crabs, etc.
Ther is a lot to be still discovered in the natural ponds around the creeks and shortly we are going for a fishy trip to the ponds and collect some specimens. |

Well
Wetweb media has a brackish section.
However it says that normal salt cannot be used, seasalt has to be used.
what should be the sp gr of the water in brackish aquarium.
Further is it possible to graduate from freshawater to brackish water to a marine water in term so maintenence of tanks |

sandeep your idea of graduation in the hobby is indeed appreciable. But, my dear friend each aquatic environment poses a unique challenge and IMHO you cannot compare any one part of the hobby as easier than the other one!
Indeed, to maintain a marine aquarium you need to be more conversant with the water quality and the chemistry. But, to think that a brakish water system will help you understand the salt water chemistry better is not fully true!
there are many diverse aqautic environments and each has a unique chemistry - as I told you above, I could find fish in brakish habitats which were absolutely not supposed to be there in the first place - fish like sea bass and moray eels are just an example of how versatile our aquatic friends are at adapting themselves to diverse habitats!
So to understand the subject - study 'it' rather than studying something similar to 'it' |

Sounds like fun. Let us know what you find.

scats and chromides do well in freshwter also.For a brackish water its necessary to add a little brackish water to your tank first to set the water cycle going. |

They may survive but will never thrive....its sad to see scats and monos being dumped with other regular freshwater fish... |

Surviving is one thing, living comfortably is another thing.
Brackkish envoirnemnts are at places where rivers empty into seas, sea water sureges inland into rivers.
The water chemistry is forever changing and has different levels of salt at diffrent times.
The fiahes living in these water have adapted to various water conditions, they can "survive" in pure freshwater but will not be comfortable in it.
Further at juvinile stage both scat & mono can live in ferehwater but will need brackish water as they grow up. |

Sandeep, as I told you it is very difficult to determine what fish you can get to see in the creeks and the swamps as they sometimes come from the sea and sometimes from the FW source - but they live happily in the brakish conditions.
It is very difficult to say that xxx amount of salt should be added to the FW to make brakish water, because the chemistry of the brakish habitats is ever changing. It is one habitat that is largely dominated by the tide and ebb times and the lunar cycle. |

Okay, Nauzur, agreed
Then how do perole who maintain brackish systems maintain salinity.
IAH must be having blokes keeping brackish water setups |

Well, Sandeep I think you should analyse what exactly you want to keep than start researching on what habitats the fish belongs to and what is the water chemistry..........try replicating these and bingo! |

So nauzer can you write a detailed post on what one must do if they wanna start a brackish water tank from scratch...i mean basic tank size,tankmates to say monos which are probably the most popular brackish water fish,substrate,decor etc etc...i have been tugging at the idea of having a brackish water tank but cant trust the lfs here.. (one of them though it was a great idea to dump monos with oscars  )
and speaking of adaptability..how can we forget the good old molly..afterall is it not a brackish water fish to begin with?  |

Brackish water setups can be a little hard to define because the salinity varies by quite a bit for different fish species.
Monos, scats can be kept at around 1.005 - 1-010 spgr.
Puffers go all the way from 1.000 to full blown 1.025 spgr which would probably be more towards the marine side.
I guess it depends on the species you want to keep. |

7.0. They cannot survive in sea water. Temp -24-28 deg C
Plants
Best/hardiest brackish water plant species: Microsorium pteropus-Java fern, Hygrophila polysperma – Dwarf Hydrophila, Sagittaria spp.- Dwarf Sag. Vallisneria spp. – Giant Val, Echinodorus tenellus – Junior Sword /Pygmy Chain Sword, Ceratopteris spp. – Water sprite,
