Just a bit of an update, the bitaeniata are doing ok; they got camillanus, so had to treat them with levamisole, and haven't spawned since, so I think the worms mucked them up a bit. However, since then I have got a pair of A.sp. pebas, and just a week or so ago got a pair of panduro. These two have given me a nice surprise of eggs this afternoon which is cool. Here's some photo's:
