Retirement and forum shutdown (17 Jan 2022)

Hi,

John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.

I wish to thank John for his hard work in keeping the forum going.

With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.

I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.

If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.

I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.

I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.

Thank you
Darragh Sherwin

LAKE MALAWI/NYASA

If you ever get a chance to visit the Lake Malawi formally Lake Nyasa the one thing that will amaze you will be the size of the lake.

Lake Malawi is a massive body of water. It’s far more like a sea than a lake which is what early European explorers thought it was. Lake Nyasa was visited and named by the Scottish missionary David Livingstone in 1859.

Lake Malawi/Nyasa, the third largest lake in Africa, is bordered by Tanzania in the north and northeast, by Mozambique in the east, and by Malawi in the south and west. It's has a surface area of 11,600 mi2 (30,040 km2) making it the ninth largest lake in the world. The surface area of Ireland is 70,280 km2 .

This lake contains more species of freshwater fish than all of North America and Europe combined.

The lake is 360 miles (580km) long, its only 281 miles (450km) from Cork to Derry so you can see if you travel the length of Ireland you would still have another 130km ( Derry to Belfast + 20km) before you would get from one end of the lake to the other.

At its widest point the lake is 15-50 miles (24-80km) wide, same distance as travelling between Athlone to Portlaoise. The lakes maximum depth is 2310 feet (704 meters) making it the 4th deepest lake in the world. You can stand 2.3 Eiffel Towers end to end in the lakes deepest part.

I hope you can understand the list below but I couldn’t get my chart onto the web page. B)

Name and location sq. mi. km mi. km ft. m
Victoria, 26,828 69,485 200 322 270 82
Tanganyika, 12,700 32,893 420 676 4,708 1,435
Nyasa / Malawi 11,600 30,044 360 579 2,310 704

Very interesting Tom. It's only when you see those statistics that you realise we don't realy have lakes here, they're more like puddles. We don't have mountains either, just hills!

Regards,

Ken.

I suppose most of the fish don't swim in the first 30cm just because an aquarium is this depth. What is the main bulk of the fish living at (depth in metres?????)and more importantly what average temp. I know when I dive without a wet suit in Majorca in August its 28C at 1M but at 18M its 23C with the thermocline at 11-12M, basically at 11M its 26C and at 12M its 23C, and under the thermoclime the water is more still wave and currents are probably similar to the Med during the Summer calm.

That would be a ecumenical matter!!!

From what I could Google these are the temperatures of Lake Malawi.

The surface temperature of the lake ranges from 76F (24C) to 85F (29C) and the temperature at lower levels of Lake Malawi is a constant 70F (21C).

Hi Have experimented with different temps, and found juvenile fish need 24to25Cdo well, perhaps the feed in the shallows, but the adults prefer 20to 23C, at this low temp they don't get bloat, with the SAME feeding re grin mixing malawi and Tangs the Dubois get bloat and some die, reduce the temp and zero problems.

That would be a ecumenical matter!!!

I also found out on the web how Jim davidson got the chalky expression from, its from people that live near the chalky lakes, which gives the hardness and alkalinity.:laugh:

That would be a ecumenical matter!!!
