  1. When you find them they are normally in large numbers. Yes they are normally found in the faster flowing, highly oxygenated water. And yes it's often cold. They can be quite a sensitive fish. On occasions I've had them dying in the net before I can release them (a matter of seconds). But once you have them conditioned to your tank they seem to do quite well if you maintain stable conditions. So high flow, large tanks, and stable conditions seem to be the key.

  3. For anyone considering catching their own Mangrove jack, be aware that they are a sport fish with size and bag limits. The minimum legal size is 35cm, and you can keep a maximum of 5. Alive or dead doesn't make a difference. If you catch a small one (less than 35cm) and think "this will look nice in my tank", be aware that you are breaking the law if you keep it.
  4. Styrofoam fish box, double black plastic garbags. Don't bother with oxygen or air pumps.
  5. Thanks for letting us know. I'll check it out this weekend.
  6. Leo,

    I spoke to you a little while ago about swapping some honey blue eyes. I am in Toowoomba next weekend and I was wondering if I could swing buy and swap some? If thats it ok, how many females would you like me to bring?

    Thanks again


  7. Ornate rainbows (Rhadinocentrus ornatus), Crimson spotted rainbows (M. duboulayi), Pacific blue-eyes (Pseudomugil signifer), and Hardyheads (Craterocephalus sp.) are all natives that will survive outdoors and in unheated tanks during winter in your area. Those will also breed in a planted tank or tub. Maintained in a single-species environment, some of the fry will survive. In a community tank they won't.
  8. If they are just for display, I'd stick with all males. If you think you might breed them at a later date, keep uneven numbers of males and females; at a 1:1 ratio the females can receive too much attention and lose condition.
  9. Agreed, although I'd add to that description: Males - Pointed fins that extend all the way to the caudal (base of the tail fin) Females - rounded fins that stop short of the caudal.
  10. They have been used effectively for years, but I don't use them any more. I think you're better off with a powerhead (with sponges) or small canister. I don't know the design of your coffee table, but you can easily incorporate a small power head if you section off a corner/portion of the tank, blacken the sides so you can't see through it, put a lid on it so you can't see down it, and then all you need are entrance and exit holes for water flow. What are you plans for lighting?
  11. Sorry, not at the moment. I think this has been my worst year ever for breeding. I raise all my fry outdoors and the temperature has just been too variable. One week the weather is nice and hot and I've got lots of fry, the next week the temperature plunges to 12 degrees and the fry all die. That happened at least three or four times this summer. As a result the only fish I've been breeding in any numbers are rhads and honeys. Best source for werneri is Dave Wilson at Aquagreen in the NT. I'll see if he can send some down for the next ANGFA QLD auction.
  12. What is the minimum recommended temperature for keeping guppies?
  13. The next Australian and New Guinea Fishes Association (ANGFA) QLD meeting is programmed for Friday 13 April. Gavin Brown will be speaking about turtles and Greg Ure will speak about his fish-farm tours in Singapore (following Aquarama). ANGFA QLD meetings are held at the Bar Jai Hall in Clayfield, Brisbane (Alexandra St, near the intersection with Sandgate Road). Meetings are held on the second Friday of every second month, starting in February (unless they clash with a public holiday or long weekend). Meetings start at 8.00 pm and usually end at around 11.00 pm. Meetings generally consist of two talks and end with an auction of fish and plants. We run a drink stall, a raffle, and a small shop that sells fish food, plastic bags, nets, books, etc. We conduct Field trips at various times during the year so that our members can catch their own. You can find the ANGFA QLD website here: The Home of ANGFA(Qld) - Home
  14. I only discovered these fish recently while exploring north of Tin Can Bay. The majority of the fish from this creek are not particularly noteworthy, but a small number have a colouring that I think resembles a praecox as they have a blue/green body with red fins. So I refer to them as the Praecox rhad (they are totally unrelated to praecox). I'm breeding these fish to try and stabilise this colour morph.
  15. The Teewah Ck strain is one of my favourites. The dominant colour in Teewah Ck is red tail with a redish-bronze front. There are also some pure red fish. When the males are in spawning colours the fins are black or black edged. Gunther Schmida image (my fish) Gunther Schmida image (my fish) My image
