My Corys used to be active all day. Now they hide until the light goes out... then they are active as all heck.

Normal or not?!

The tank is heavily "planted" with silk plants...

my corys are funny little suckers they work during the day and play when the lights go out. sometimes though, they park themselves like jets on a runway for an hour doing nothing.(sleeping maybe? they look cool like that though:D)water parameters are fine. and they only do it for a little bit

i just did a 30% water change yesterday...

not perked up when the lights are on.... when they go out, they go nuts though...

*shrug*

always hide in the same bushes too. maybe they just call it home during the day?

only thing i can think of if they aren't afriad of lights is that i have a mixture of very small gravel and medium gravel. the medium gravel is bigger and harder to dig through for the smallish corys. all i can think of?!

well, its a possibility they aren't afraid of light, but simply me...

i took post on the stairs 20 ft from the tank, lights on, and watched them run all over the place...

soon as i walk within 5 ft. of tank, they bolt to their bundle of bushes.

did this a few times...

so, i guess they are normal...

Well my 3 panda corys don't usually come out at all during the day unless it's feeding time. Their base camp is this shady spot at the far end of the tank next to a big piece of vertical driftwood used as a home for my 2 clown loaches. They camp right next to the driftwood under a little patch of java ferns. This seems to be their "safe zone" where they feal more comfortable when fealing threatened.

As for their activness in the tank I noticed several things since I watch them carefully every day for at least 10 minutes. Ive had them for at least a year or 2 now. One, every time I do a water change or clean the gravel, they come out in an instant and start mulling about. I assume they like the freshness of the new water being added, as well I think they like to hang around for scraps when I use the gravel vacume. It makes sense. Second I also noticed that sometimes they will actually shoot up to the surface of the water in the tank and then dive back down. This is an interesting behaviour that I noticed. I guess they do this when they feal especially good.

Also in the last couple of months I have also noticed that they are much more active and sociable with their tank mates in general. In the past when I would feed my fish they would be timid and usually wait for the other fish to finish eating before they would start searching for food. Now they come right out when it's feeding time and they don't take s&it from my other fish :). Especially my bad tempered, overweight algae eater who always has fits during feeding time. The biggest of my 3 corys which is not far off from being 2 inches in length will stand up to my algae eater and not run away right after recieving one of the algae eaters token "charging head butts".

They are pretty much individuals. I have found the julii cories are pretty active day or nite. Two or more of the same species seem to keep them more active in the daytime. I would agree, there have been instances of increased activity after water changes.
