Hi all! Prepare yourselves, for I am caffeinated and chatty to begin with. Actual stocking ideas below the indented text! I've been keeping fish consistently with minimal hiccups the past several years. Currently growing out some feeder goldfish (I love seeing them get bigger!) and a mosquitofish that came in by mistake on one of our feeder shipments when I worked chain pet retail. Rubbish job, but the discount was nice, it gave me great ease of access to the hobby, and I was able to buff up the fish department by correcting many wrongs. Before I left, I managed to snag a 120 gallon tank and a Fluval FX6 for $300 total on Black Friday with my discount. I've done tropical fish in the past and would really like to get back into it, as much as I love my goldies. The tank is currently sitting in storage but I am finally able to move it out and get things set up soon now that I've got an actual job.I was thinking of doing a blackwater tank, with a decent sized group of a large statement species, a large group of a schooling species, and something with shoaling behaviors for the bottom of the tank. I've looked into the care requirements for the following species and I'm confident in my ability to take them on. This stocking checks out on AqAdvisor, but I'd like to hear some feedback in case I overlooked anything. My thoughts were:6 half-black angelfish (see LiveAquaria)12 bronze cories18 cardinal tetrasAll of these would be added gradually, of course, and I was thinking to add the angels 2 at a time after everybody else has been established, using my quarantine tank at first, just because I've seen too many angels come and go with ich and other issues. I'm open to suggestions for changes, my only caveats being that I'd like this to be sort of a biotope tank (Amazon river species, blackwater preferred) and my heart is set on angels. I'll admit my biotope idea hasn't been thoroughly researched so the right species could change my mind pretty easily, but I love angels. I guess the questions that remain are:Are cardinal tetras big enough to avoid becoming an angelfish snack? I wanted neons at first but AqAdvisor was concerned they'd be too small to house with a full grown angelfish. Cardinals checked out, but they don't really get too much bigger, do they?Would the output from the FX6 be too much for the slow moving angels?Beyond that, if anyone has plant recommendations, specifically for floating plants (besides anacharis, I already buy it by the bundle for my goldfish to snack on), please let me know!
