Im thinking about trying a butis butis species tank and have a couple questions. First, what salinity do they prefer to be kept at. I've researched and really havnt found the the preferred gravity. Second, where can I get one of these? I dont really know where to start or if their seasonal. Lastly, what plants (besides mangroves, grow to slow) can be put in a brackish tank? Any other info you guys can give me would be great.
