My cory swims up and down the glass of my tank rapidly ever so often is there anything the matter

[Maj0rFiSh]

Maybe they wanna get out cause their enviroment is so small. Or thwy are just hyper, mine used to be, but now do jack ****.

Its just burning off excess energy, I'd think, someone on here says his female cory does that when its about to lay eggs.

If swimmfins is right, I'll be having lots of eggs! haha, I have 4 bronze cories, and they do it too, well 3 of them do, the other 1 swims around the bottom of the tank. How many gallons is this tank? Mine is a 10g

[jnr102030]

6.5g and i only have 1 n thanx 4 da help

If I were you I would pick up 2-3 more of the same kind next time you get a chance, cories tend to like being in groups. GL!

I would agree, however a 6.5 gallon is a bit small for a group of them. What species of cory do you have jnr?

My panda cories do that all the time. As far as I can tell they're just chasing their own reflection. It seems as though the longer they are in there the less they do that. Also, my most active one does it the most, so SWIMFINS' energy burning theory may be correct.

I would suggest you assess how many more cories you can fit in your tank and then get that number, they are a shoaling fish. They feel much more secure in numbers. Here's some good info on schooling/shoaling behavior.

mine do this and clean the glass too(they're not underfed believe me). Since moving them to a bigger tank, my cories do this less and less, now they swim against the current to burn the steam off.

They can breathe atmospheric air, so they will go up to the surface for a breath once in awhile too.

why does everyone say that cories should be kept in groups? I have one and it is loving it!!!!!!

the cory also swims around like a psychopath. about 3 months ago i lost every single fish in my 15 gallon while i was gone for several days. they got some weird disease from a betta that i introduced. he was living with dead fish for 5 days. i came home and thought that everything was dead. in the corner there was a finless cory still kicking!! I did masive WC's and cleaned up the aquarium and is doing great. his fins took a full 3 weeks to regrow all the way.he has gotten enormous since the mass death........

They're way more fun to watch in groups. When they're laying around the tank, one of them will just shift, then the next one will too, and it just starts a chain-reaction of retardedness.

I planted painstainkingly, some nice pygmy chain sword, that looks alot like little grassy stems. Well, I had no sooner put 'em in place when these three cories decide to go bounding through it one after the other like little kids in a pile of leaves. Well, fishtanks are for fish ain't they? So I bit my lip and kicked the couch..... :o Luv the cories.

[congealedmeat]

lol Swimfins, mine hang out in my bacopa all day. Just laying in it, hanging out with the shrimp. Guess it beats laying on gravel :D

indeed it is a breeding response wich in your cories can be triggered by partial water changes with water about 5 degrees warmer or cooler than than the current water this will trick them into thinking the rainy season has come andthey will "clean" the glass to lay eggs. the eggs are vulnerable to fungus but if you use a mild fungicide at half strenght they will hatch. ive successfully breeded cories in a community tank and a species tank but heres the thing

they do all that cleaning to lay eggs but they will lay "dummy" nests of eggs that are not fertilized!!! then hide the real eggs!! to trick their predators and i must say my fish love picking those eggs off the glass!!! also when the males get into "heat" there tails may turn reddish slightly easier to see with albinosS
the eggs will hatch in 3 to 8 days depending on tempurature unfertilized dummy eggs turn white remove them they will also eat there dummy eggs after theyve laid the real ones!

keeping one cory by itself is cruel they are like dolphins or elephants and are matriarchal they depend on there school like a wolf pack or lions. do your fish a favor and get him a few friends meany!!!

One of my cories has recently started swimming upside-down at the surface of the water and gliding all the way across the tank like that when he goes up for a little breather. It's hilarious!
