Hi all.

Got bored of my guppy tank (3 years up and running) and purchased 3 albino corydoras of about .5" or a tad larger. (10g, 78oF, pH 7.2, nominal metabolites.)

Although since they're new to the tank and chasing the corners hyperactively, as new fish usually do, will they calm down a bit in time, or should I expect them to be zooming around most the time? What I'm seeing worries in the least due to the amount of food they may require with such a rate of activity!

Thanks!
 
Mine were zoomers for the first couple of days. Now they spend most of the day at the bottom grazing slowly. They still zoom around in the evening for about 20 minutes which is amusing (once and a while one or two will go nuts for about 2 minutes at other times). So expect them to calm down. They are great fish to keep.
 
That sounds normal. After they get used to their tank they don't go quite so crazy all the time, though they do manage a good spastic swim now and then.

My blind catfish is an albino cory and she is definatley the most spastic of the group.
 
Thanks all. I suspected as much.

After years of keeping cichlids, all it took was some cory's to make me feel noob again! Oh, what a feeling!

One day later, 2 of the three are still zooming. The third is zooming, but will take a second here and there to nuzzle the gravel occasionally.

these are the first LFS fish I've bought in 3 years. I just hope they don't show signs of 'new fish syndrome' (accumulated stress.) I'll just leave the lights out. The guppies, who have never met another species are actually curious about the new arrivals. Just what I needed! A little 'newness' in this tank.

thanks again!
 
spastic corys

I recently got 4 Anaeus (sp?) corys, and they were very spastic for the first day or so. They still spazz if I startle them, (easy to do!) and when I move too quick. They have settled down quite a bit in the 3 days that I've had em, they mostly graze around the bottom industriously when I watch em. (they still zoom a bit for no apparent reason on occaision.)

From what I've read/heard about corys, thats just how they are. I enjoy watching em. I've seen mine (and read elsewhere) that they will occaisionally zip to the top of the tank and grab a gulp of air, too. (I can understand my gouramis doing this, they have that labrynth organ thingy.. but why corys?)

neat little buggers.
 
Cories can actually grab a bubble of air and swallow it and later digest it in their gut. That is why they sometimes have huge swollen bellies.
 
I have four aneus cories that are either lazy or active, depending largely on how much food is on the substrate. They spend most of their time sitting beneath the plants or the plecostimus, but when food hits the water they go insane!
 
My experience with cories has been a good one. I have 4 bronze cories (Anaeus) in my 20gal tank. One of them whom I named Greenbow, I've had since May of 2002. The other two, I've had over a year. They love to stick together and swim along the surface together come feeding time. Sometimes, they will zoom along the glass walls, but most of the time they just rest. It's really fun to watch them swim against the current of my filter!

Greenbow has been through 3 tank setups and lost his barbels, but somehow he has managed through the worst. He's made it throught disease, temp fluctuations, failed algae tanks and various other debacles. The other three still have their barbels. They are tough little guys. I'm thinking about getting a couple more to have real schoal (sp?).

They've been the best tank mates I've had... :)
