To take care of problems like this you could put a little "Barbecue Salt",these salts used for prepare the meat before a barbecue. Sorry, but I dont know the correct name in English. It is an excellent remedy against bacteria and fungi. Always use this salt in my aquas. What type of food you offer? Live food or granules?
I am to build a tank for the reproduction of Bichir de Cuvier (Polypterus senegalus) at home, but must decide the location with my wife, who is also biologist. When I start the assembly of approximately 300 liters for a couple, put the photos here.
The BBQ Salt sounds like a great idea.
I feed a wide variety of pellets from 3mm to 9mm in sinking and floating format. Also they receive a lot of flake food. I have a very large and diverse cichlid population reproducing in the 52k providing live food for the hungry predators wanting to try and catch them. I feed also large amounts of cut up mackerel, pink salmon, herring, whitefish etc. and from time to time smelts also.
I have no bichers at the moment but did grow a large P. ornatus to over 20" and gave it away to a friend who really liked him a few years ago.
I do have 3 lungfish.
2 African P anectens and a Australian Lungfish that I got from my friend Neoprodigy. The first 2 each have their own 180 gallon and the Aussie has a 359 gallon tank. They are all kept alone at present with just a shoal of guppies to keep them company. Both African Lungfish have had suitable tank mates in the past when in larger tanks.
It will be interesting when you get results from breeding your bichers.
As I was loading some of my lungfish pics I added a few of my peacock bass taken I believe in either 2007 or may be early 2008. So now my friend you can maybe identify his species for me.
