I recently added 6 x Rhomboocellatus Barb and 6 x Black Phantom Tetra to my tank of 6 x Zebra Danios.

I noticed on Monday evening the new fish had white ’salt like’ spots on them.  Yesterday I was at Silverstone but I did manage to purchase a bottle of King British WS3 treatment on the way back home.  By the time I arrived home (midnight), the Barbs & Tetras had died.

I have removed the dead fish and carried out a large water change.  I’ve added a dose of King British WS3 treatment and will continue the medication for another 10 days.

The orginal Danios are all swimming about quite happily. Water conditions have remained at zero ammonia and zero nitrite and the temp is currently 27c.

Having seen a colleague’s aquarium and those at my local fish shop, and doing a bit of research, I decided to get my own tank for the sitting room and start to look after some tropical fish.

I ended up buying a Fluval Uno 800 Aquarium, measuring 80×30x40cm (internal volume approx 75 litres) which came as a kit of parts so I got the heater, filter etc with it.

Tank all set up and settled in, I bought six little Zebra Danios on Saturday.  Will allow the filter etc to get used to the new additions for a few weeks before buying any more fish.
