I recently noticed that one of our silver hatchetfish is missing an
eye. How would this sort of thing normally happen, and can he get
along okay with just one eye? He seems to be able to find food all
right.

There's nothing in the tank that would have attacked him, I think,
other than another hatchetfish. I do have a male betta, but he's never
paid any attention to the hatchets and they are quicker than he is
anyway. I have some glowlight tetras and rummynose tetras, but they
don't go up at the top where hatchetfish stay. I can't imaging my BN
plecos or skunk corys would have had anything to do with it. The only
other thing I can think of is the otocinclus, because they sometimes
try to attach to a pleco, but I think the hatchets are much too fast
for that. Since hatchets can be jumpy, I guess he might have poked his
eye out jumping up against a decoration, but I don't really have
anything sharp. There is no sign of disease with any of the fish in
the tank.

Thanks for any ideas or advice--

How: either against a decoration, or against the cover underside
during a jump, or from a fish, or from bacterial disease which cause
the eye to protrude making it more likely to get pulled away.

Can he get by without it? The fish probably doesn't even know it's
gone anymore. They seem to rewire their senses fairly quickly. If it
was an adult, you might notice his stance becomes a little crooked
when he is staring at you. Otherwise, they are so strongly wired to
their sense of 'hearing' through their lateral lines that vision may
even be secondary. They can still eat in water we cannot see
through. Blind fish (cave barbs) which genetically have no eyes or
eyesight, have no problems swimming or eating.

If anything, this fish has been promoted. ;~) It's now more
recognizable (you'll be watching for him), and it has more
character. : )

Okay, thanks. He seems to be getting along fine. The area where the
eye was is healed over, so I guess it happened a while ago and I just
now noticed. He is the jumpiest one of the five hatchets but maybe he
just got jumpier when he lost his eye, or maybe that's why he lost it.
I know he has hit the cover once or twice when jumping.

Yes, I guess he is "promoted" because I take special care that he gets
his share of food.

If you had an angel, I would guess that was the culprit. They will
stalk and stalk.

It is nice that it is doing well anyway.

No, I don't have any angels. The hatchetfish seems fine and the area
is healed, there's just no eye there. He seems to swim, school and eat
like a normal hatchet.

Bottom posted.

I had a 15 gallon with one male betta and one telescopic eyed black
goldfish once. One of the telescopic eyes of the black goldfish was
entirely removed and ate by the betta - the male betta had a big bulge
for a stomach after that. Unfortunately the black telescopic now one-
eyed goldfish soon died from that one wound and loss of an eye and its
stalk. I saw no blood but these are fish after all. This took place in
my start in this hobby when I was around 12 years old. I did have a
rough start in this hobby like a lot of newbies and not so newbies
alike. Good luck all and later! P.s. I never witnessed the aggression
but I know it is what happened because of said bulge.

It is possible that the eye came out and the betta just ate it. = )~

Sorry to hear about your goldfish. My hatchet fish is still fine, but
losing an eye for a hatchet probably involves much less physical
trauma than for a fish with big protruding eyes.
