Help! My Fish Are Dying

[Marco84]

Yesterday evening I found a dead Lemon guppy at the bottom of the tank (he looked so healthy the night before swimming around looking for food)
Today doing my fish number count, I see my Neon Red Dwarf Gourami dead at the bottom of the tank! (he even looked healthy 12 hours ago)
and 2 of my leopard skin coloured snail eating loaches (forgot their offical name) look sluggish and leaning to one side slighty

What do I do? Any Ideas what is going wrong?


Some details about my tank: It's an Aqua one 510 (80 litres) It's been set up 8 weeks. 1 week without fish, 4 weeks with x7 White Cloud mountains until the water quality past. Been slowly adding the other fish over 3 weeks.

The other fish are

6x endler's livebearers
6x lemon guppies
5x lamp eyes
1x Dwarf Gourami now
2x leopard skin loaches
2x Singapore Flower Shrimp

They all seem healthy apart from the loaches

Their diets are Tetra Prima slow sinking Mini Granules, sinking wafers and algae wafers

I been doing a 10% water change once a week and put aqua safe and live start in the new water
Water heat is 24

It could be a bacterial infection.
Do the fish look bloated or skinny.
What does it look like when they go to the toilet.
Do they look pale or darker in colour.
Any signs of flicking and rubbing or laboured breathing.
Any excess mucas on the gills or body of the fish.

What are your water stats in ammonia, nitrite, nitrate, and ph.

White Cloud mountains look a little bit plump but they always get the lions share of the food. The others look of normal size compared to pictures.
Looks like a long string when they go to toilet
They look of normal colour to my untrained eye
The loaches sometimes rub their sides on the gravel and sometimes start to breath faster.
I can't see anything growing on any of the fishes
I just had my water tested in the shop for nitrite, nitrate and ph and was told it was perfect.
I was told to do a 15% water change everyday for a few days, is that right?

I would go out and buy some liquids test kits as you can't always trust certain lfs.

Long stringy white poo can be constipation, bacterial, or internal parasites.
What do you feed the fish?
How often are the fish rubbing.
Check the anus of the fish to see if it looks enlarged or red and inflamed.

 

[Marco84]

It's long and browny coloured
I said in my first post what their diet is
About every hour they have a good rub

 

[WILDER]

I would take a sample of your water to the lfs and ask them to write the readings down for you.
Need to rule out bad water quality as it can cause flicking and rubbing.
You need to improve the fish diet of frozen foods and veg.
Does the fish look bloated.

Cook some frozen peas for a few minutes, Let cool down and pop out of shell. Mush into small peices and add to the tank.

Definitely go to the LFS and ask them to write down the exact numbers when they test the water. Ask them to test for ammonia as well, that's one of the most important ones. It sounds like your tank might not be properly cycled.

Another one of my Lemon guppies died today, dead upside down at the bottom of the tank

Brings the total in 4 days, 2 lemon guppies and 1 dwarf gourami

I have noticed the other dwarf gourami keeps nipping the dead body, could it be the problem of the deaths?

 

[WILDER]

Fish can catch desease when they peck at a dead body.
Until we know water stats it hard to say. As flicking can be signs of bad water quality.
