Experience in tropicals

Hi guys

At one point I had a whole house of tanks from breeding zebras and guppies for food (sorry) to Miami garfish and a tank full of tiger Perch. I kept an African knife fish at full size and to this day it was the most veracious predator I have ever had. It puts all the Puffers such as the fahaka's in the shade. I mainly specialised in oddballs such as garfish and my speciality polypetrus of all morphs. Bass was another favourite of mine and the humble clown fish. Cichlids being my favourite.

 

I did them for 30 years since the days of the bottom gravel cleaners but 5 years back sold all my tanks and my leccy bill dropped by £150 a quarter.

So if it’s OK I might dabble in here now and again I still enjoy the odd chat about them. Not too many guppy subjects though ...;)

That's it mate. The Garfish i had never needed any heating either .

 

This year i want to get some perch fry and subject them to tests etc. I know Steve Burke did this and i am interested in doing it myself. Also if the tank is filled with the water they came in the bacteria is already there in the filters...Easy.

When I was a PhD student at the FBA, we have a new postdoc who wanted to study young of the year perch and pike. He got some from Windermere (he hadn't used a seine net before, so I gave him a hand) but the perch just failed to thrive - really nervous and jumpy whenever someone walked near them. Someone told him that the fish from one of the other sites were much easier to keep - I think they were from the Great Ouse - and indeed they were. So if you have trouble keeping perch fry from one water, try some from somewhere else!

possibly somewhere with a lot of noise/activity ?

Maybe, Andy, but these were very young fish that would not have had time to learn anything. I think they were probably just a less twitchy breed. Maybe it's more of an advantage to be a twitchy nervous fish if you are growing up in a clear lake rather than a muddy river?

I certainly think there's something in that Steve.

 

Also, I think the density and variety of predators would have an effect on the behviour of the fish from a particular water.
