Flicking On Gravel

[Harlequins]

hi all

i've noticed the past few days that a few fish have been flicking against the gravel,i've seen 2 platies and a cory flick their back/side against the gravel?
Now i've looked at various diseases but i'm not sure which one to treat for?

The fish in my sig all seem active apart from the harleys don't seem to be shoaling just dithering in one place maybe looking has though they may be twitching??
I cant see any spots etc on any of them?
Am i worrying unduly?

Help please!

Tank 48 ul gal,stats ammonia/nitrite 0,nitrate 30,ph 7.8/8.0,tank temp 25.6
nothing new added for 2 weeks.

What test kits are you using.

Is there a greyish film on the fish or a bluish film on the fish.
Do the gills look pale with excess slime or red and inflamed.
Any signs of darting, erratic swimmng, excess mucas on the fish.
Can you see any red pin prick marks on the fish.
Any scales look lifted on the fish.

Api liquid test kit,one platy appears to have a white mark on her side,she's has it for about a week but i'm not sure if its just the light reflecting??

Can you describe the white mark.
Does it look like bleaching beneath the skin or fluffy looking, or a talc dusting.

Added any meds to the tank lately. Anything that could be irratating the fish.

Do any fish look bloated or thin.
What does it look like when the fish go to the toilet.

Can you describe the white mark.
Does it look like bleaching beneath the skin or fluffy looking, or a talc dusting.she's a red platy seems like bleaching under the skin,then when she turns it looks more like its sticking out,sorry bit hard to describe
Added any meds to the tank lately. Anything that could be irratating the fish.- i did add interpet 9 for internal bacteria a few weeks ago due to cory deaths,but i didn't dose again and have done a 30% w/c since
Do any fish look bloated or thin. platys,tetras and corys look ok,the harlequins look a bit thin,they don't appear to eat much anyway
What does it look like when the fish go to the toilet. i have only noticed the platys poo,sometimes it looks a bit white and stringy

I have been trying to see if they seem any different,apart from the harleys not shoaling just hover around and apart from the red platy with her white mark,the white platy with black spots(this one was flicking at gravel) and the blue platy,i not sure but they look sort of pale and it seems as though they have a red streak running along the spine inside? does that make sense? i only noticed it with the light on.
They seem active enough feeding,hunting around the bottom,nibbling at algae

The corys and tetras seem very happy they're spawning!

But i just don't think they're ok and the flicking worries me.
Thanks

Do you have any snails in the tank?

Red streaking on fish is due to bad water quality, septicemia.

Do the fish show any of these signs.
Long stringy white poo or clear mucas poo. or red poo.
Enlarged red inflamed anus.
Worms prutruding from the anus.
Fish will look skinny or bloated.
Fish will sometimes swim on its side.
Bent spine.

For now I would add a bacterial med to the tank, Sounds like septicemia, and the bleaching beneath the skiin might be columnaris.

Long stringy white poo or clear mucas poo. or red poo. long stringy poo a few times,but haven't seen any recently
Enlarged red inflamed anus. no
Worms prutruding from the anus. no
Fish will look skinny or bloated. neither,like i said harleys have looked slim but i wouldnt say skinny?

Bent spine. no

Dinner time i put interpet 6 anti white spot meds in has i noticed my orange platy had 2 small white spots on her,i've treated the whole tank,after turning the tank blue for a while the harleys perked up and have been shoaling all afternoon,whether this is good or bad i'm not sure,its certainly nice seeing them swimming again instead of dithering.
I will keep an eye on them and see how they go with this med.
I have turned the airpump right up and the tank upto 27 degrees,i am a bit wary of this because of the cories.
I had the tank temp set on 26 for a long while although it was reaching 28 when we had a hot spell,after losing the corys a few weeks back i turned the temp down to 24 it goes up to 26 when the lights are on then drops back to 24 overnight,would this cause problems with the fish has the temp is up and down all the time?
Thanks for your help so far

Are the spots the size of a grain of salt or bigger.
Any redness to the spots.
The parasite med will kill the snails so remove them if there dead. As they can become toxic to fish as they rot.

The black spots can be caused by snails.

Black Spot



Symptoms:

Your fish will have small black spots measuring about 2 millimeters in diameter. These can be found anywhere on the fish’s body and fins. Cysts may be found in the internal organs. It is typical for African Cichlids, however, to constantly have little black spots, especially around their mouths. These black spots should not be mistaken for "Black Spot." These are scabs, which have resulted from digging in the gravel or from fighting.



Cause:

Larvae of parasitic digenetic flukes, Cercaria and Metacercaria. The spots seen contain larval stages of digenetic flukes. The life cycle of these parasitic flukes begins when fish-eating birds and other animals ingest fish infected with the parasites. Once ingested the parasites mature in the intestines of the host animal where they produce eggs. The eggs are then deposited into the water where they hatch and infect the livers of aquatic snails. The parasites then develop into a second and then third larval stage before leaving the snail to seek out a fish host. This type of parasitic infestation is most common in wild caught fish and pond fish.



Treatment:

Remove all snails from the aquarium or pond to end the cycle of infection. Treatment is rarely necessary and can be difficult if not impossible. Minor infestations may clear without treatment as the larvae will eventually die and be absorbed by the host's immune responses. Copper Sulfate may be helpful in severe cases.
