The Festival of Fishkeeping. It's an annual event hosted by the FBAS and is held on Hayling Island - usually the second week of October.
Has most types of fish there for showing, some for sale, trade and craft stalls and informations stands, such as UKAPS one

Thank for clarifying, Ilaymir.ilaymir said:Hi George;
The tanks are small+Some of the rocks are quite large+There is little water
The rocks used, looks like easy to dissolve in water.Especially the iron compounds they contain, oxides easily and spread out particules all over the tank.That is why in such tanks water changes and cleaning of the glases are needed frequently.
Thus,such problems are obvious from the brown formings at the corners of tanks which are not cleaned well.
Thanks, Mark.saintly said:personally no.1 is brilliant. classic iwagumi.
no2. amano stylee nano/small tank
no.3 potentially, genius
no4. a great GE scape.
good work guys. I'm a little envious.
ilaymir said:Hi George,
-What I wrote are my general thoughts about the tanks.
I said "I believe in you" because I know that petrified woods are quite suitable for tanks.
But then I trust t my own experiences and observations.Because these rocks are not that innocent.
As petrified woods take form they are efected from surrounding.Minerals and organik materials in water enter in them.After that they petrify by help of microcrystalline quarts(silicate).That is why they contain elements like calcite,iron,magnesium,manganese,zinc,cobalt..etc.
Colour of the rock shows what kind of an element it has.If it is yellow,brown,red like on the photos it has iron oxides in it.If it does not have too much pyrite in it,there is no problem,iron that oxides spreads around and causes pollution.That is the case.Also instensive silicon dioxide(SiO2) is one of the main causes of brown algea(diatom).
-Tanks at the photos you send are cleaned before shoting.Even though you can see some at places I marked.
-Some of petrified wooods -especially brown and yellow ones- contains "carnotite".And "carnotite" is an "uranium" mineral.
In fact I found some of them suspicious.Personally I would test them with a "geiger counter".
