Well I'm fairly certain that it wasn't this way before i feel like i would have noticed it before. And hes been adult since January. If that helps this possibility at all
Rainbow fish curved back
Okay its 147mgl not sure how that converts but someone else can probably do it
Had he been netted before it appeared? Or dropped? It could maybe be an injury

I'm sure you can and are able to keep them with no problems at all
It was adult when i got it I believe to my knowledge no bent spine at that point so it wasnt birth deformity. I dont know if scoliosis is from birth or can onset later in life.
No he was just in the tank like normal for about a week then bam the random darkness
It looks as though mg/L and ppm are equivalent Essentially
I did do a water change that day but just did a siphon no gravel or moving things.
I would assume because the building was built in the 70’s and the pipes probably have calcium or some other mineral buildup making the water fall on the harder side
Tap water can have a high pH because bleach/ chlorine is alkaline and water companies add things to the water to keep the pH above 7.0 to stop pipes rusting.
You can have very soft water with 0 GH and a pH above 8.
The pH has nothing to do with this issue and captive bred rainbowfish are fine in water with a pH over 8.5. Melanotaenia boesemani actually come from a lake with a high pH.
--------------------
Melanotaenia lacustris (turquoise rainbow) go dark at night time and can look black in the morning when you first turn the room light on. This is normal nocturnal colouration for the fish. Many other fish change colour when it's dark.
--------------------
The M. lacustris is sick. He has flared gills, clamped fins, excess mucous and gunk on his mouth.
This is caused by poor water quality, chemicals in the water, or external protozoan infections. The flared gills are usually caused by poor water quality or gill flukes.

The best treatment for rainbowfish is salt.
Add 2 heaped tablespoons of rock salt, sea salt, or swimming pool salt for every 20 litres (5 gallons) of tank water. Keep the salt in the tank for at least 2 weeks but no longer than 4 weeks.
If there is no improvement after a couple of days with salt, increase the dose rate to 4 heaped tablespoons of salt for every 20 litres of water.
If you do water changes, add salt to the new water before adding it to the tank so the salinity (salt level) in the tank remains stable.
-------------------
Increase aeration/ surface turbulence to maximise oxygen levels in the water.
-------------------
If you have an established filter (from the 20 gallon tank), move some of the filter media into the filter on the big tank (55 gallon). This will give you a cycled filter on the big tank.
Put all the rainbowfish in the big tank and treat them with salt.
Put the female Bettas in the 20 gallon with the Corydoras and some plants.
------------------
Rainbowfish and other fishes do better with bigger water changes. In future I would recommend doing a 75% water change and gravel cleaning the substrate once a week. Removing a large volume of water will help to dilute disease organisms more effectively and reduce the chance of disease outbreaks like this, which I reckon is an external protozoan infection and gill flukes.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank.
Rainbowfish are sensitive to chemicals and chlorine/ chloramine can kill them if they are exposed to it.
--------------------
If you want rainbowfish, try to have even numbers of males (eg: 2 males, 4 males, 6 males, etc). Make sure the males are the same size to prevent bigger males bullying the smaller males.
Try to have a similar number of females to males.

Its just that this rainbow has never turned dark like that before i did get to take a picture last night of what looks like a white spot with a almost cottony/web apperance the two spots protrude the surface of body about equivalent to a pimple that needs popping.
