Caught Dr Harry doing a stint on sea horses and how to cycle an aquarium fish tank for them.
Harry used a "cooked & peeled" prawn (and he stressed a 'cooked & peeled' prawn - not left over prawn scraps) to kick it off - he then said not to add the fish for another 6 weeks - presumably so that newbies didn't toss fish in too early, but it could be that using prawns takes that little bit longer to cycle - nothing was said about removing the remains of the prawn before introducing the sea horses or if it should just be left to rot.
One point that I would like to stress though and that is this method was used for "non eating" fish, I do not know if any bad types of bacteria etc would be introduced to our tanks where we look at eating the produce (both plant and fish), so use prawns if you wish but just be aware
For the international members - Dr Harry is a veterinarian and does a weekly show on pet health/behaviour problems and how to remedy them.
(sorry Dr Harry if my description is not spot on
)
At least the sales people there explained they needed a different tank and refused to sell them when the person refused to buy a suitable home for them. I wonder how many less scrupulous sellers are out there.
