Are My Albino Bronze Corys Blind

[ZoddyZod]

My Albino Bronze Corys seem very unaware of food or other fish until they touch them (often getting a tail whip from the BN when they get too close). Are they known to have bad eyesight?

All cories have bad eyesight and often use their barbels to find their way around. In my aquarium it takes them a around 30 seconds to sniff out algae tablets but this is normal.

I knew they used their barbels to locate food, but I didn't know how short-sighted they were. Comical to watch when they land on the face of my BN.

from what i believe corys have excellent eye sight. most originate from the amazon river that is very murky and tanned from dead plants, leaves etc etc.
food wise any ive kept never go mad for it like say a group of tetras would, they are very steady eaters and will eventually find what they are looking for

Thats the reason because of bad eyesight, in the Amazon River its very muddy so most animals that live in the river have bad eyesight. Take the Arapaima or the native Pink River Dolphins.
Most Corydoras come from Rio (river) Orinoco which has also very dark water.

there are many fish species living with in this water that have excellent eyesight tetras, piranhas, pacus, angelfish, discus, numerous catfish species, freshwater stingrays but to name a few all have very very good eyesight. just because they live in tanned water doesnt mean they have bad eyesight. there are however fish that use other senses to guide them like knifefish. a corys barbels are for finding food not for guidance.

Living in murky water the corys have excellent eyesight or they would not survive.

Thats a good point but Cories and other catfish come from dirty rivers , while Tetras, Rams, Angelfish, discus and freshwater stingrays come from creaks that has clear water. The Pacus and Piranha come from the same type of enviroment as cories and have bad eyesight like other fish there. Which is why Piranhas dont hunt with eyesight but sense of smell. Thats just my opinion.

hm...one of my albinos has ended up getting sucked up by the hose twice when cleaning out...my blacks and peppereds always manage to see the hose coming and get out of the way. I don't know if it's bad eyesight or if that particular albino is just more stupid than usual. My other albino tends to dodge along with the others.
