zombieworm Posted May 19, 2016 Report Share Posted May 19, 2016 A couple of weeks ago I bought 2 albino corydoras. I had them in the 400 ltr tank, but they seemed unhappy there - large, dark gravel substrate, and boisterous yo-yo loaches. So I moved them into the 160 ltr tank with white sand substrate, and more placid tankmates. They certainly seem to like it. My question now is - do anyone else's corys do this? Mine seem to LOVE doing this. JJWooble 1 Quote Link to comment Share on other sites More sharing options...
JJWooble Posted May 19, 2016 Report Share Posted May 19, 2016 Omg hahaha that's hilarious, tho are they fine after doing that?None of my sterbais have ever done that as far as I'm aware, so your corys may indeed be weird, even for corys zombieworm 1 Quote Link to comment Share on other sites More sharing options...
gligor Posted May 19, 2016 Report Share Posted May 19, 2016 My cories often try to dig into the gravel, however my gravel is made up of small stones so not that easy to dig into it as it is in fine sand like in your tank. They do however manage to push at least part of their bodies down in the gravel... especially when food particles fall through the cracks!

Caryl Posted May 19, 2016 Report Share Posted May 19, 2016 They are well known to like to dig into substrate and prefer a nice sandy one so burrowing is easier. They can't do that on gravel so such behaviour won't be seen unless you have a sandy substrate. It is important that whatever you use does not have sharp edges as this will wear down their barbels.

zombieworm Posted May 19, 2016 Author Report Share Posted May 19, 2016 There were 2 salt and pepper corys in that sand substrate tank already, and I have never seen them do that, or the julie corys in another tank with sand substrate. So the first time I saw one of these little guys sticking out of the sand like that , it freaked me out. They frantically wriggle into the sand, and just sit there like that, totally still for a few minutes. Then suddenly, their tail will flop to one side, then the other side, then they pop out. It is so funny to watch. Also, all the other corys I have stick strictly to the bottom of the tank, but these guys swim all over. They also periodically race to the top to take a gulp of air. None of the other corys do that either - not even the salt and peppers in the same tank. Their behavior is so different from all the other corys I have.

cyclonenat Posted May 21, 2016 Report Share Posted May 21, 2016 My albino corys are mega active they surf the bubbler and zoom around the tank zombieworm 1 Quote Link to comment Share on other sites More sharing options...
Caryl Posted May 21, 2016 Report Share Posted May 21, 2016 Racing to the top to gulp air is a common trait in some corys.How active, and whereabouts in the tank, can depend on tank size and how many corys in the group. Usually, the more you have, the more active they are. JJWooble 1 Quote Link to comment Share on other sites More sharing options...
Poppie Posted May 26, 2016 Report Share Posted May 26, 2016 Hahaha that's so cute!Mine just dig down to the top of their noses, not all the way in like that, I'm sure it fine though Quote Link to comment Share on other sites More sharing options...
