In the UK pet animals act and the animal welfare act say that animals require adequate space and housing So technically there are a lot of people breaking the law, (it is the reason why you don't see goldfish in a bag at the fair any more). But the issue comes down to policing. They can even get...

Do you work with Animals in the US? from my little reading in the US it just covers mammals (wow.. backward... -_-) I can't speak for the US, however all vertebrates (and now Cephalopods) are covered in the UK under the scientific animals act. And as such it is highly regulated, highly...

No, I am sorry that is not true. There are established protocols within fishkeeping which have been demonstrated scientifically

Ok steady on everyone. I am all for challenging the status quo in attempts to improve the maintenance of our aquariums. But: 1) you should not be experimenting on fish, this is against animal experimentation laws and requires licences, ethics reviews by appropriate qualified people 2) If you...

No worries :)

The water change time probably makes up most of the time you interact with your tank, its not a bad thing to be reduced.

I don't disagree with you I said as much in my first post. You have the same amount of bacteria in a larger area, as the waste production supporting that population is the same. However where I think it might be beneficial is having media which is already biologically active rather than...

Of course, Hence why I stipulated with its more complicated. That being said we could talk all day about the possible issues with hormones, proteins and ANF's ect excreted into the water to name a few. But despite all this a good start point for people to look at a WCS is the things we can...

So I think that's what he is doing, and just wanting to add extra media into the filter to buffer the loss of cycled surface area on things not being moved between tanks eg glass.

It's not necessarily the size of fish, but what is it "for". I find personally the best comparisons are with adult stocks which are planned for brood stocks, these fish are being kept for longer periods of time, not for growth but to be healthy and robust enough for breeding purposes. Hence I...

So the way I work out a water change schedule is to test my tank for the rate at which nitrates increase So for example if my nitrates go from 10 to 20ppm in a week then its increasing by 10ppm a week ( I test over a few weeks) Now if you have a desired Nitrate level eg below 20ppm then you...

Yeah, So moving across the media and fish then waiting will allow the bacteria on on the new media to expand and form in the new tank. The extra media can help with this. Then after a while the media can also help with excess surface area with the new additions. But will al biological...

Exactly, I have a friend who works in biofilter biology and mechanics during the transition from freshwater to salt water in Atlantic Salmon and I understand nothing of what she says :rofl: I wanted to use it as an example that the biomedia and nitrifying bacteria is a complicate subject...

I agree, and I think it is more widespread than most think. In aquaculture feeding rates are about 3-4% per day of body weight to achieve massive growth rates even for a 100g fish that's only 3-4g of food. ( water exchange on this by the way is massive!) For adult stocks feeding is reduced to...

Well I suppose that depends on the desired effects :rofl: . By putting in the extra biomedia you are increasing the available surface area that the nitrifying bacteria are able to colonise. As long as it had a good amount of flow over it and doesn't clog with waste it should provide that...

I mean that would depend on your setup, 1 guppy in a 150 gal is not going to be producing a lot of waste, add plants to that mix and the Nitrates will take ages to build up. But in all cases even prolonged exposure to low levels of nitrates can have serious implications for long term fish...

Yeah due to the size I thought more along the lines of non infection, IME that sort of wasting doesn't happen fast. but then again we would need a time frame? They look quite young so I wonder if it is aggression or maybe a husbandry issue.

See the issue is still you are comparing two different things, try and keep your comparisons to fish if possible. The species studies for aquaculture is quite large and while not directly comparable eg Cod to say a Angelfish. you can often make a sensible comparisons eg Tilapia to a barb as...

I don't think we need to jump into medications straight away. The nitrates are a little high, as a rule of thumb i try and keep mine below 10 ideally 5ppm That being said some extra information wont hurt. How long have you had them, they look quite small? What's your regular schedule? It does...

Not me, It's good to talk about this. I come from an aquaculture background so my opinions and experience (while also in Ornamentals ) is also in the husbandry of food fish. IME there is a lot both ornamental and aquaculture can learn from each other but rarely any crossover

Because you are applying a mammalian requirement onto a fish, their requirements are not the same as how you would feel if you had to go without food for a week

Yeah so If you look at Tilapia, which is probably one of the most widely studies warmer water freshwater fish. (also a herbivore) the perform better with more regular feedings however the level and frequency have been shown to be reduced at increasing size feeding for growing fingerlings is...

With respect, comparing pet fish to their natural habitat is more correct than doing so to comparing humans. Please do not equate your mammalian requirements to that of your fish. What you think a fish "deserves" is not necessarily what it really requires. And while comparisons to fish we...

So Update for anyone looking at doing the same in the UK, If you want to fly fish out of the country you have to use a service who fly pets out. I used Extrodinair based in Edinburgh. and they were brilliant, there were issues with contacting BA but i think in times like this getting hold of...

There is certainly a lot more coming through the journals, it's all the data that people are sitting on, the "oh i will do that when I have time" data

Thanks, My contract with work ends in Sept but I cant even get back to the university so we have been allowed to work from anywhere. My partners contract ended in May so it wasn't the best time for things to be ending, but these things happen. I have to say it has been a very good time for me...

Thanks i will have a look into it all when I am sat in a house during my 2 weeks quarantine! Moving in Covid times is not an easy thing.

Thanks all for the advice I think things are finally looking about right with the shipping and it seems that i will have to go through a pet travel company rather than pack myself. I will outline my experience in a thread for future people when I am done. @Byron, thanks for the info that is...

Thanks Colin, The packing side is easy I have all that sorted, I have packaged fish for fish farms to transport (national and international), when I used to work at a hatchery in Scotland. The trouble i seem to be having at the moment is actually shipping them. And limited flights due to a...

Does anyone have any experience in Shipping fish? I am due to move from the UK to Canada, and while I am aware that it might be easier to re-home in the UK but With my long-lived fish it would be the equivalent of re-homing a cat or a dog and I would much rather take them with me. I am aware...

Inbreeding depression is also a factor, if these individuals are highly related then there could be a high level of mortality due to inbreeding depression such as documented in Zebrafish (Mrakovčič & Haley., 1979). Or in Convict cichlids (Winemiller & Taylor., 1982) Mrakovčič, M., & Haley, L...

Many aspects of lighting has been demonstrated for many fish species as having an effect on behaviour, development and sometimes even growth as well as many other things; Heydarnejad, M. S., Fattollahi, M., & Khoshkam, M. (2017). Influence of light colours on growth and stress response of pearl...

Here is the cover of that book, I have to say it is useful and quite easy to navigate. ( as opposed to the Red one A-Z of Tropical fish.....) That 1908 one doesn't but the one by Bateman does have a similar suggestion. Whenever I pass a second hand book shop I always keep an eye out for...

I like to scan the old bookshops because you find some interesting little gems. This book from 1908 with these beautiful illustrations.

A snapshot of my fish "Library" It is nice to see people using Martin A Moe's book. Although It is marine, a lot of the DIY in the systems book is really useful.Most people I know who work in Aquariums have that book somewhere. The DK one Fishmanic posted I saw while I was in Canada and thought...
