This year, we have had a very harsh and severe winter. Unfortunately, some fish, who were in poor condition when they went into the winter, did not survive. Others, who have been weakened by the prolonged cold spell will emerge in the spring with depleted strength and not in the best of health.

I’m sure you may all remember the last August bank holiday of 2001, the Saturday was a really nice day and Sunday was pouring it down, just typical of the UK Bank Holidays. Well, for myself I shall remember it for a different reason, as you will read on, that Sunday I lost virtually all my beautiful Koi collection, probably my own fault, or was it just a tragic set of circumstances!!!

There are many issues that can cause concern to our fish, this article, whilst by no means definative, aims to give you an indication of the main areas of concern to keep an eye on.

For a couple of weeks I have been a bit concerned about my quarantine tank.

The fish were a bit off colour and not taking food at all. I put this down to a sudden drop in temperature as when I tested the water it was ok apart from a slightly high reading of ammonia.
