Sick Guppy

[seangee]

Hi All

Yesterday one of my female guppies settled on the bottom of the tank and stayed there. I moved her to isolation in the same tank as my isolation tank is full of fry. Here is the full history

About 6 weeks ago I noticed she had a bent spine.

3 weeks ago moved into a new tank with a cloned filter. Two weeks ago the nitrite spiked and I lost another female guppy. This morning she had deteriorated but was still alive. Her body had turned grey / black and I had to put her out of her misery. This week I noticed my male guppy had split fins and all the guppies were gasping, other fish were fine. He had white growths around the tail fin cuts so I treated with anti fungal. He and the other guppies seem fully recovered now.

Tank is 300l. Ammonia 0, nitrite < 0.1 (40% changes daily). Nitrate 25 (same as tap water) and ph 8 - also the same as the tap. Temp is 25 C . Tank has 3 guppies remaining with 3 platys, 4 platy juves and 6 cardinal tets

1. Any ideas what happened to her
2. 3 of my platy juves are hovering at the top corner - unlikely to be low oxygen in the tank as they had a 60% change this morning
3. The other platy juve is right at the bottom
4. Could this behaviour be related and if so how should I treat

The anti fungal treatement has completed and I did allow for the water I was taking out in the changes. I'm not sure whether to continue treating with the anti fungal, treat for somethng else or just stop treatment. I'm pretty sure water quality is a factor and I have moved some more filter material across from the fry tank. I just really don't want to lose any more fish

Bent spines if not born that way means old age, fish tb, to internal parasites.
Are any of the fish producing long stringy white poo.
Check the anus of the fish to see if its enlarged or red and inflamed.
Any worms prutruding from the anus.
Any fish look really skinny or bloated.

You can a slight nitrite reading so I would do a water change.

Greyish film on the fish can be columnaris to parasites.
Any excess mucas on the fish.

Is there plenty of aeration in the tank as meds reduce 02 in the water.

No other symptoms that i can tell. The guppy was a bit skinny and earlier in the week there were some long stringy poos but they were normal colour. No sign of them now. This morning I changed 60% using a bucket so I don't think there is a real o2 problem right now. The one on the bottom has now moved up to join his mates in the top corner.

The fish had internal parasites with the bent spine, being thin and long stringy white poo.
The problem is you need to treat the tank for internal parasites, but for camallanous worms you need a vet to perscribe a med.

Summary of what I know.

It may be a parasite.
I have lost two fish in two weeks. The first two to succumb were possibly the weakest in the tank and now it may have affected the very young.

I have only once had a parasitic infestation about 6 years ago and it wiped out a whole tank. I have seen a number of posts on here recommending not to treat for something unless you know what it is. So what is the general recommendation here. I am thinking perhaps a general purpose parasitic treatment. I can't start one until after work tomorrow anyway so as many replies as possible in the nect 12 hours or so please. The juves are all still in the top corner (tightly huddled together).Any opinions on their prognosis.

Its hard to say if a fish has tb and its not showing all the signs of tb.
Livebearers are prone to camallanous worms.
There is a internal parasite med you can buy but it dosn't say if it treats camallanous worms.

Thanks Wilder

Good news is the platys were a lot better this morning and even better this evening. I have decided the safest option (of course I may be wrong) was to treat with Sterazin as it seems to treat a wide range of parasites and doesn't affect the bio filter. This last bit is quite important to me as I am almost at the end of a mini cycle and don't want to put myself back at square one.

Cheers

The waterlife med no good on internal parasites I used that med years ago and it did absolutely nothing.
The wormer plus won't even knock your water stats where the waterlife med could.
