Spotted gar acting weird

[Giwrgos1991]

Hello guys,
I have a spotted gar around 30cm in a 200 gallon tank. I had it with 2 kois and a pleco, but i decided to remove the kois and turn it slowly into a predator tank.

So the changes i made: i removed the kois, i removed the subtrate and i added a steady schedule with 8 hours lighting in the tank (because i got some plants, previously i turned on the lights randomly).
This happened 10 days ago. So now the gar is in the tank alone with the pleco.
Since then the gar is acting weird, but im not sure if this started a little before i made the changes.
It is not eating at all, it is laying still in a piece of wood all day and when the lights turn on it starts swimming around at night.
It seems completely healthy but it is not eating and is staying still all day.
Tank temperature 20 degrees celcius.

Anyone knows what might happening?

I have 6 florida gars which are similar and have had so for a number of years. It is odd behaviour but indicative of a not happy fish. I once had this but the gars were being sucked on in the night by a flagtail that was sucking their mucus off. It effected their behaviour and they remained still at botttom a lot instead of swimming
You've made a lot of changes there in a short space of time so maybe it is that

I know they can withstand cooler temps but would it not benefit from warmer water mine are in 28

I have a pleco also in the tank which is smaller than the gar... I have never seen him sucking the gar and the gar's skin has no marks... also the pleco is in there for a lot of time... is there any chance this may be the issue? the gar at night is very active and during the day i've never seen anything...

nothing else has changed...the other thing i can imagine is that it feels lonely? which is super weird because the kois were harassing the gar a bit all this time...
