My large tinfoil now leaves ferns and anubias alone, so I'm pretty much sticking with those plants. The 3 Dennison's seem to leave plants alone, but they are only around 4 inches. I wanted to add at least 3 more, but the only ones I've found locally are 1 1/2 inches - which is snack size for the bichir and sunfish. Plus my big tinfoil might try to eat them.
I did add about 25 rosy reds last week, but the sunfish and smaller bichir (haven't moved any of my larger fish yet) picked most of them off. I deliberately netted the largest because they were a little bigger than the Dennison's at work, and I was hoping that they'd be ok. Nope, so if I want more Dennison's, I gotta grow them up in a different tank. I also bought 3 small tinfoils, who immediately started following the sunfish around. I added 20 more rosy reds (2 of which immediately got picked off) and 2 more tinfoils yesterday. Checked water parameters today - .25 (maybe) ammonia, 0 nitrite, and around 5 nitrate. Nitrate dropped significantly, but I also changed the filter pad and vacuumed out a ton of hornwort debris.
I'm paying close attention to the water parameters, but needed some fish to get this beast going. Water changes won't be an issue, they are just very time consuming because I get to play Queen of the Bucket Brigade.
