  1. The metal cage provides all the strength as the thin plastic acts like a liner (only). So if you cut the cage, you will need to reinforce the compromised cage again. Either with a strong surrounding frame around the new open edge or some cross braces. Could use wood or wire as a cross brace. The deeper you re-fill, the stronger the new bracing needs to be. There are a few aquaponic forums that show IBC modification pretty well. Earth, gravel or clay ball media is heavier than water but it's the same principle.
  2. Oscars are notorious for sulking. From your description it sounds like you are over feeding.
  3. I use nylon bird protection netting (Bunings) as it's cheaper and much easier to pull out/clean.
  4. Growth Inhibiting Hormone.
  5. Yes... all the selection, compatibility and guesswork has been done already. Very good idea isn't it. What a great time saver.
  6. Aren't gambusia an Australian native fish? I've seen them in almost every creek or dam I look at.... And if they aren't a native fish, they will be considered to be in a few thousand years. Just look at the dingo.
  7. I use masking tape to make a small tag which you can write on. Wrap near the plug end. I also put the plugs in a certain sequence so those that never need to be turned off don't get bumped. I used to dyno label the power points to match the plugs as well but the masking tape label is all i needed so i stopped.
  8. TILKEY at Coopers Plains (Brisbane) sell plastic drums of all sizes. New and used. http://www.tilkey.com.au
  9. Deeper ponds dont fluctuate in daily temperature as much as large volume ponds which dont fluctuate as much as shallow or small ponds. At the start and end of brisbane winter, day temperature can be 30 degrees and night temperature can be 10 degrees. A 20 degree rapid change is hard for all fish, cold water, cool water ir tropical. I have salmon tail catfish outdoors. I use a heater set to 18 degrees at start and end of winter to stop the fluctuations and turn heater off once the weather settles.
  10. Sounds like his swim bladder is damaged, either by rapid temperature change or physical injury. I don't think epsom salts is going to do anything, it's more for fish that float. I would just keep the tank dark and see if he recovers. He may not make it, or he may survive without fully recovering. Might even make a full recovery - depending on how badly damaged and how tough he is. Best wishes!
  11. Most people do prefer perfect bars so if you are selectively breeding to suit what most people like/want then the "Y" stripes are culled and the female throwing them not be used anymore. Similarly a dark lateral line spoiling the white band is usually avoided. If you personally like the "Y" stripe and don't care what others think then do what you wish. However if you only have space to raise say 500 babies, then why not keep the very best 500 fish?
  12. I would use an air driven sponge filter - very established (a food source in itself) and try either live baby brine shrimp or vinegar eel. Live food is instinctively recognised and more easily consumed. If baby brine are too large then infusoria culture slow dripped over gentle air stone. Elodea (plant) creates areas fry can hang out near food and the micro life on the plant itself is useful. If dripping infusoria, keep using the same constant place as fish learn where to sit to catch food. Feeding very small fry isn't hard but there is a steep learning curve. Read up on how to feed rainbow fish fry as most of that is directly transferable. Most issues come from over feeding so you need to watch their bellies. Once you have a few eating, the others copy. This can be useful teaching the next spawn by adding some experienced fish in, especially if you weaning onto dead foods.
  13. Have you asked Dennison? He moves large tanks all the time.
  14. Sump is much noisier, prone to evaporation (and salt creep) increasing humidity, takes up a lot more room and can create micro bubbles. Canister is even worse...
  15. I suspect the difference between osmosis and osmoregulation has been mis-interperated or misunderstood. Freshwater fish are hypertonic so they fight to keep salts within their body. Most of what has been quoted applies more to saltwater fish and this may simply be a mis understanding however there are still some significant errors. Resistance to medications is a very real issue though so again, the more choice in treatments available, the better.
