i recently rescued 4 fish from someones tank i met this weekend. he had not fed them much and did not have any filters or air bubbles for them at all for about 6 MONTHS. there was one jewel fish two plecos and a catfish i have not indentified yet.also there was only about 6 inches of water left in the 55 gal tank. i put the plecos and the catfish in one of my tanks but the jewel would get eaten so i put him in 5 gal for now.i didnt know fish could adapt to no air or water movement. has anyone ever heard of this for this for this amount of time?
