Corydoras always so scared when someone approaches

roxyfan

My corydoras are always so scared when someone even remotely approaches the tank. They panickingly rush back to hiding spots and stay so still like statues. Is this normal behavior for corydoras?
Sometimes even from 4 feet away away if they happen to (sense "movement outside" the tank) see someone approach when they're grazing about , they quickly dart around to hiding spots and stay so still acting as if they are dead.
This is happening for different types of corydoras in all of my tanks - corydoras trilineatus in one tank, corydoras pygmaeus in another tank. They've been like this from the start ever since I got them. My tanks have many other fish too including schooling fish like neon tetras and livebearers like platies and guppies. But still the corys are so terrified when someone approaches. All other fish are fine.

Are they in a group? Corys feel safer in a group of 4-6 or more.

Yes there are 7 corydoras of each type together in a group.

Maybe for awhile you could feed them a small amount each time you, or someone else, approaches the tank. Then the corys will start to associate people approaching with something positive.

Are there a lot of places for them to hide? They'll feel safer if there are,

How long do you gave them? Mine are always a bit more sensitive and careful than the other fish as their territory gets invaded on a semi regular base during the gravel vacuum. Tak8ng a trip through the syphon dod not give them the earm fuzzy feeling. Feeding yummy stuff like bloodworms or brine shrimp trumps the fear, and they are slowly getting a bit more trusting again.

Your experience is exactly the same as mine, so I hope you get an answer.

I have kept 3 types corys in the past (groups of 6). Each tank had plenty of hiding places, plants and hardscape as well as other fish that were happy and unspooked by movement around the tanks, but the corys would frantically scatter and hide with any movement anywhere in the room. This behavior never changed and they lived for several years. I stopped keeping them because I never got to enjoy them.
