  1. Hi there, I would recommend to look for parasites on the fish first up by performing a skin scrape and a gill wet mount. This type of chronic mortality can be due to ectoparasites- and it is not uncommon to introduce new bugs into your system if you add stock regularly. If this does not give us any answers, then we can look at further diagnostics such as histopathology. Please PM me if you would like a quote.
  2. Have there been any other fish introduced into your tank that could have had contact with the L134's? (aside from the broodfish) I would recommend we look further into it to prevent stock-loss- we could do some more diagnostic tests to see what could be causing deaths. In juvenile fish, even some parasites can gravely affect them because of their size. Let me know if you are interested and I can let you know how much it will cost. Thank you,
  3. Hi, Are there any other L134's looking "sick"? - reduced feed consumption, lethargy, redness, skinny?
  4. Hi there, I would opt for the salt bath at 5ppt (5g/L). Fungal infections are difficult to treat, but sometimes they come good with prolonged salt baths. Fungal infections usually cause breaks in the skin of the fish, causing the salts from blood to leak out into the environment causing osmotic stress. Keeping salt levels ~3-5ppt will assist in reducing the osmotic stress and may help with the fungal infection. Need to look at underlying stressors that can cause fungal infections to take hold- have there been any changes in environment?
  5. Hi there, What are you using to treat his fungal infection? and how severe are his lesions?
  6. Hi there James, It is probably best to get it checked out and see if it is actually a Hexamita infection. It could also be primary trauma followed by a secondary bacterial infection- we could figure it out by swabbing the lesion and having a look under the scope (+/- staining). Once the cause is determined then treatment w the right antibiotics or an anti-protozoal can assist healing (depending on cause).
  7. Hi there, These are definitely koi. They have a small collection in the Chinese Gardens- it is legal to keep them in NSW and WA. There are many classes of koi and they make pretty great pets!
  8. Hi there, We sell aquaculture supplies and have pH 4, 7, and 10 solutions ready to go- if you would like a price on them, please let me know- we can give you a quote. We can send by express post to you and you should receive it in 2 working days (max). Cheers,
  9. Hi there, If you are interested in identifying them, we can help you out. I will only need the pictures on the web sent to my email and we can get an algal specialist to look at them. The macro-algae are not normally harmful, but it also means that you may have excess nitrogen/phosphorous in your tank. If you are interested in looking into it further, please feel free to PM me. Cheers.
  10. Hi there, Looks like they are some type of water-flea (daphnia or rotifers)- they are great protein for juvenile fish and are used regularly to feed finfish larvae. They can bloom quickly in a pond if fertilised (with a nitrogen, phosphorous, carbon source). If you could get a clearer picture that would be useful. How large are they? and do they exhibit a flickering motion? Cheers,
  11. Hi there, Do you have a photo of the broken pelvic fin? The circling swimming motion can also be caused by CNS disease. A complete history would be good if you have the time to call the clinic. If you would like to speak about it further, please call Future Fisheries Veterinary Service- we are a Vet service just for fish- ph 0450 035 001. Cheers, Christine
