Hi Martin,
Welcome to the forum. I have 3 to 4 albino gold bristlenose plecos in my discus tank. I have them over a year and I didn't have any problem. They don't get too big and they seems to do OK with the high temp and food that I used in teh discus tank. I usually keep my tank around 86F. They also do a great job with the algae.
I also added a 3 in golden nugget in the tank for a few weeks. They told me the golden nugget will do ok with the blood worm and food. My temp may be too high for them. I will have to take him out when he/she get bigger also.
I think overall the albino bristlenose plecos should be fine.
Hope this help.
