  1. A lot of rainbows superficially look very similar. They differ in detail. The rainbows around Lismore are southern examples of Duboulayi https://rainbowfish.angfaqld.org.au/Duboulay.htm The initial image of the blue and red stripped rainbow is an Utcheensis (https://rainbowfish.angfaqld.org.au/Utcheensis.htm) The red tailed rainbow looks like a morph of a Eastern Rainbow (https://rainbowfish.angfaqld.org.au/splendida.htm) There's heaps of colour morphs of them (and probably lots of species lumped into one group).

  2. Hi Al - I'm the current President, so I could be biased. As you can see, people don't really frequent this forum nowadays. I only jump in rarely. ANGFA Qld has a pretty active f/book page. Covid hit us pretty hard (in terms of meetings...but our membership grew over the period) but we're back to face-to-face meetings. Members only at the moment (to control numbers and registrations). Our shop is still open, but we have paused auctions and raffles just till we get our heads around how covid-safe impacts our meetings. Joining angfa is nowadays pretty easy - all online - https://www.angfa.org.au/join-angfa.html Ta Graeme
  3. The colour develops with age - and (sadly) the bigger and past it males have the best colour. Best to breed them young and continuously. You'll find that they will lay - and probably hatch out in a community aquarium. But the young are a bit pathetic and other faster fish will eliminate them pretty quick, not to mention that the parents will wack them as well. Hence why I'd separate them from the parents. As for flow, they are a goby, so if you are smashing around the current, they probably won't like it - but I've had them in a recirculating system with air driving filters going flat out - and they were fine. Dwarf rainbows (I assume you mean Macc's or nigrans or the like) don't like high flows. The larger rainbows (Tris, spendidas) are what live in the middle of rivers - maccs and the like prefer gentle backwaters.
  4. Desert Gobies are super easy to keep - but you'll need a bunch. 30 gallons is about a 3' tank and I've keep a couple of dozen in there. I made up a heap of caves using 2" long 13mm PVC pipe, glued in trefoil (three bits). It's amazing to see a 2" fish actually turn themselves around inside such a tight location. Keep the ends facing the front of the tank so you can see inside them. When there's a bunch of eggs, they'll hatch in a week or so - I used to pull them out and put them into another tank and let them hatch out without the male. Why - purely as my main goby tank had the couple of dozen with little cover. I assume if you had a tank with lots of structure, the babies will survive. Couple of key desert goby notes. They only live for a couple of years, and after a year, they'll stop breeding. So you'll need to breed them often - every year consistently to keep them. Miss a year and you'll have heaps of adults and zero next generation. The lovely big ones you see in the images online are the geriatrics and invariably they won't breed. The big males are gorgeous - but they just fight for domination and not for getting the girls into caves. The 2nd note is - goby young are quite fragile. They don't like being moved around until they are well over 10mm in length. Under that and they'll die in droves when moved. The only reason I got out of my desert gobies is that they were taking up too many tanks of babies (due to the 2nd note above). But they are amazingly easy to breed.
  5. I wouldn't recommend any Galaxias unless you have a chiller added to your tank, assuming you live in SEQ. There are Galaxias native to Qld namely the Galaxias olidus (Mountain Galaxias) and Galaxias maculatus (common galaxias). You find both in the upland cooler streams towards Toowoomba, although olidus is in the Condamine system, while maculatus hangs out in the Gold Coast upper catchments (although, I have never actually caught any myself). maculatus is actually spread around the Pacific and Atlantic Oceans being amphidromous. I assume that Spotted Galaxias are Galaxias truttaceus, and if they are, they are a truly gorgeous fish - which I saw my very first live ones at the 2019 ANGFA Convention in Melbourne. But those guys do prefer it being below 25 degC all the time. Just be aware that this is one of the larger Galaxiads (for Australia, NZ ones get bigger) and will grow up to 12". There are some ANGFA members in Victoria who keep them, but they aren't very common in the hobby.
  6. #3 is a M. trifasciata (https://rainbowfish.angfaqld.org.au/Trifas.htm) of some type (I'd suggest a Wonga Crk - but can't really tell). And it's got TB going by the mark on the upper left hand side flank unfortunately. #5 is a "Macc" as noted above (although technically Skull Crk varieties have been shifted into M.sahulensis). ta Graeme
  7. As Novice pointed out above - they are a "Macc" of some nature - perhaps M.sahulensis - https://rainbowfish.angfaqld.org.au/sahulensis.htm They don't look like M. maccullochi - but in saying that - they could be females - https://rainbowfish.angfaqld.org.au/Maccull.htm Ta Graeme
  8. Something to consider is that in order to heat 1 litre of water by 1 degree, 4,186 watt seconds (Ws), or 1.163 Watt hours (Whr) is required. So for this set up, the wattage (300W) and liters (600l) are known, so over 24 hours, the temperature rise can be calculated as ~14 degrees C from ambient (assuming zero losses - ie/ the tank system losing temperature into a colder room around it etc. etc).
  9. Out of interest, the Medo pump that I mentioned above in 2009 is still going strong in 2015 today :-)
  10. I got into the hobby thanks to my Dad who always had a dream of keeping and breeding Discus but never quite could do it, thanks to the regular moves that being in the RAAF forced on us. My first experiences that I can recall were looking at all the weird and wonderful things being bred in Malaysia when we were stationed over there in the 70's. Then I received my first tank (and 18" er) into which went all sorts of in appropriate things. But around Butterworth (again still in Malaysia) where all these creeks and paddy fields - and all the fantastic things we caught that I never ever saw until much later here in Australia - such as golden panchax, snakeskin gouramis, croaking gouramis, weird bettas that we called "Thai fighters" as nobody knew what they were, and lots of odd rasbora like things. Coming back to Australia I still had the "burn" so to speak and decided to stick to west African cichlids (kribs and the like). That was until 1990 when I went along to the now defunct Pet and Hobby Expo and there was ANGFA with a display of newly discovered Red-finned blue eyes. And all the other stunning fish from around Queensland and PNG. There was rhads from straddie, blue eyes from Cairns, Bosemani from PNG. I was hooked (and I'm in debt to Aquatic7 above who helped transport a poor student to/fro ANGFA meetings in Brisbane from Ippy). And since then I've been a member and locked myself into natives all the way (mostly rainbows and gertrudae), as well as getting into the activism side of things to save our waterways - and travelling the country side looking into all and sundry waterholes. Met a lot of great people thanks to this hobby. Some even on this very list :-). And looking forward to continuing to get the message out there to preserve our water ways and the many and varied things (including H.sapiens sapiens) that depends on them. cya Graeme
