alright not to try to repeat everyone else but id say the problems with ur fish are serious and all ur fault, im not sure the tank size but looks like a 55 which is barly big enough for 1 rbp, also ur tank is not cycled but idt there is nitrite or amonia poisoning tho bc there is no time for ammonia to build up and there wont be any nitrates if your tank is not cycled, you said u transported the fish in a bucket, but u didnt say how long they were in the bucket and over an hour in a car in a bucket can cause dramatic temp drops, splashing fish, and ofcourse oxygen depletion. that was ur first mistake than you put them in ur tank with out acclimating them and over medicating them to much chemicals are toxic, and by the sounds of it u over medicated a redicluse amonut which is even more stress inducing on top of the trip, temp, and chem changes. do you know what there previous tank conditions are bc if u stress them out and change the chem all at once that can be more stressful than ammonia posioning.
so what you gotta do to fix this is to add caves and at least 3-5 seperate hidding spaces for the fish to help keep stress down, turn off lights, get arid of ur plants bc they will die without nitrates and properlighting and just create more stressful nitrogens, 10% daily water changes so ur not to over due it and give your bennifical bacteria a chance to grow. make sure your temp is at least 78 degrees so that any ich or other deases they may break out with have less a chance to survive. and wait it out they should get better P's are almost impossible to kill which is unfortionate bc there boring as ****.
