I'm converting my 55 gallon tank into a brackish tank. I've bought a floating hydrometer, and a bag of instant ocean. I'm planning on the substrate being a mixture of silicate sand and the small gravel I originally had in the tank with a small amount of live sand placed on top. probably going to add live rock and plants as well. I basically got into aquariums three years ago when I saw a display of oddball and eel fish at Walmart and I had gotten away from that kind of fish, but they've always been my favorite. Since most of these fish are really brackish I'm going to try to do it right this time. I'm considering a freshwater moray, a couple of rope fish, and a dragon fish (violet goby) with possibly a fw lionfish or banjo catfish as well. I know I'll need to add them slowly. Will these fish do alright together? I was planning on having a salt level of 1.005 and a PH of about 7.8. Does the setup sound O.K.? I'ma little worried that there might be too many fish at the bottom of the tank though the rope fish and moray will explore the range of the tank at times. I really know nothing about the banjo cat or fw lionfish. I've read what your site has on the lionfish (toadfish), but couldn't find anything on the banjo at all. I've kept ropefish, dragon fish, and a moray before and have read everything I could find on the web about all three. I think all of these fish will at least be safe from each other and at least the three I'm familiar with will eat similar foods. Any help would be appreciated!
