How can I get this right?

[lolly]

Hi,

I firststly say that 'I love this Forum'

Now i have buttered you up I need more advice!

I had yesterday I was reading the Forum notices & feeling pleased with myself for not having any problems or questions to post. Today yet again I need help.
Here is the story:
Got home to find 'big' cloud minnow dead with tail & eyes eaten. Ok this is not a problem I thought he is nearly 2 years old & he had been looking depressed & ill for 3 weeks, not responding to medicine, tonic, salt or water changes. So I was sort of expecting him to go.
Later in the afternoon 'big' leopard Danio has red blotches over his body & is only swiming in bubbles from pump. Here we go again I thought! So I medicated with anit-white spot, the type I have is also supposed to be quite effective on slime & velvet as well.
I don't want any more fish to die the trend i have had in the past seems to be that a fish gets ill then dies, I think I have the tank sorted then it starts again.

BTW pH7, Nitrite 0.5, amonia 0, nitrate 5

I know nitrite is high so changed some water, before medicating.
Will do test again tonight!

What am I doing wrong?
I try to do things for the best & follow advice but I dont seem to be able to keep these fish happy.

If they are red patches on the fish it's septicemia, it's hard to cure, you will have to act fast, can you issolate the fish and use a broad spectrum antibiotic.

Just noticed you live in england so you will need anti internal bacteria med.

I lost a Danio yesterday he did not even seem ill. @ last check Danio with red bits was still living. Will get some internal med tonight, any recomended brands?
Also I think I am giong to loose Male guppy, who is just generally lethargic & is not as interested in food as he was. Does this sound internal as well?

We are away over xmas for four days, so i imagine i will loose fish I am getting really upset about this.
If it carries on I might give up the hobby my nerves can't take it. Even tho this tank was supposed to be a birthday/xmas pressie for my Fiance, i seem to do all the worry!
