Just thought i'd share with you my humble tank, 650mmx400mm
I have had the glass tank for years with goldfish in it.
Several years ago the goldfish were moved to an outside tank and tropicals were introduced to this tank.
It took me about another year to get around to building a stand for the tank, total height of around 1430mm.
Six months after the stand was built and tank set up, a split developed in one of the side seams. Panic reigned for a while and then all fish were transferrd to my "Nappy" bucket used for water cycling. My local petshop hosted my fish for a month whilst I refurbished the tank, replacing all RTV sealing.
When I collected my fish, I had a new one in there, as per the photo. It is about 75mm in length, but I have no idea what it is.
It occasionally chases some of my other large fish, but dosent attack them. Just swims as fast as lightening.
My clown loach is a dag, often sleeping on its side, one crazy fish.
There are many others that I will introduce when I can capture them on film.
My biggest is a Plex (sp?) that is around 200mm in length! started as a small fella around 20mm long when introduced to the tank.
I want to replace this tank with a larger one so I can have propper communities of fish, I will be looking at one around 450x450x900mm in size, again custom making the cabinet.
