How to make a extremely shy fish come out more?

It sounds strange to me, are you really sure that your newer Parrot didn't harass Pinky at all (maybe when you were not watching them?) because 'to me' it sounds as if Pinky is frightened to be hiding 24/7 and not even coming out for food. They 'can be' aggressive so i'm wondering if when you changed them over to the new Tank whether the newer one claimed the territory (completely)

You could kind of test this theory out by putting in a Partition, place the newer Parrot in about a third of the tank ,wait for a while & see if Pinky comes out but. give it some time for Pinky to realise they are seperated. If Pinky eventually does come out and act 'normal' ,myself I would leave the Partition in place in the hope that he will gain some confidence & lay claim to part of the tank.

I really don't think this Parrot is 'shy' (it wasn't before) I think it's frightened.

That's what I would try ,We are not watching our Fish 24/7 and my strong gut feeling is Pinky has been harassed while you were not seeing this happen

It's worth a try don't you think as it's not much of a life hiding in a cocnout shell 24/7?

If Pinky did decide to appear,you have your answer, i would then leave the Partition in for some while but, not permanently then when it was removed I would really 'watch them'

The "playing" is most likely hunting. In any case, the yoyo is a very social animal that needs more than 5 to stay healthy and happy.

Parrots, and pink. I'm assuming this is that weird hybrid fish then. Bit much 2 in a 55g. These guys reach 8 inches quite easily and can get really grumpy if they age. Is this an American style bare tank? Or is it decorated and maybe even planted? The serpae will need plants.

Arrange some shelter, territorial boundries, maybe a few floating plants and see if that helps, it often does.

I'm going to start by saying I've never owned parrot cichlids and know very little about them specifically, but I had a VERY shy pleco do the same thing. I tried a lot of things so I'll just give you some suggestions that seemed to work for my plecos. Rearrange the tank and maybe add a few more hiding spots similar to her favorite one. I did that for my plecos as a last ditch effort to get him (Buddha) to come out and as crazy as it sounds, it seemed to work. He now can actually be seen frequently going from cave to cave and sometimes chilling on top of his rock caves. Also maybe try enticing her with favorite foods out in the open. Hopefully she comes out soon. It sucks having a shy fish. Good luck.

that's probable stressing him out everytime and too a lot stress can decrease their immune equipment and lead them to extra at risk of affliction. The bowl i'm confident is extra helpful then the cup they save them in on the keep even though it nevertheless isn't what's ultimate for the fish they actually would desire to have a tank with heater and clear out.

the shyness does stays for a while as i've gone through it many times , once with a rainbow shark , the other time with a betta and with a blue ram cichlid too.

and you know what i used to get worried about them each and every time , i don't want to advice more as i think you would've cycled your tank.There isn't much to tell but what i CAN advice is..

-do change the placement of the decorations.

-turn off the lights for 2-3 days , that has worked with my RS.

but it may seem a problem as you mentioned 3 months.

check the hardness of your water if that may be a problem?

WELLLLLLLL if I were a fish, and some HUMAN put me in a glass prison, I would't want to come out and see their face every day!
