Can I put a Corie In my tank?
Hey All,

I've never been that involved with catfish, but after being bored at work yesterday I jumped into the Cory Picture thread and I think they're amazing. I have no idea about compatibility in my's what I got:

20G Long:
6 Neon Tetras
3 Black Skirt Tetras
2 Silver Sailfin mollys

do I have room for any cat fish? I've been looking for a bottom dweller and I really like these guys.

Like I said, I do not know anything about cories or catfish for that matter. Any help is welcome!!

Yes, you've got room for cories. I'd look at the smaller species and get 5 to 6 of them.

Sounds good!!! Thanks Tyy!

A couple things I should probably say.

1) Cories are scavengers. They will eat uneaten food that falls to the bottom of the tank and they will devour another fish if it dies in your tank (serioiusly, I don't think they even let it stop twitching). They are not algae eaters. They will not eat detritus. They need a sinking staple food that is made for scavengers, not algae eaters. Tetramin and Hikari both make suitible products.

2) They prefer a sand bottom. Cories have delicate barbels around their mouths. These can be easily damaged by sharp gravel or even gravel in general. Its not to say you can't have them with gravel but sand is far better for them.

3) They are usually nocturnal. Don't be surprised if your cories spend all day hiding. It's pretty normal. Mine are most active right before lights out.

4) They need a good hiding place. Since they're nocturnal they rest during the day. They like a place they can hunker down in that's dark and lets them feel safe. My pandas spend most of the day huddled up under a fake tree root that has some hanging plants right over it to keep the light out.

5) They are schooling fish. Cories perfer the company of their own kind. They're most active and enjoyable when they have other's to school with. My pandas rarely leave each other's sides. Always shoot for 5 to 6 cories, of the same breed, at a time. Cories generally don't mix and match. They do occasionally but don't count on it.

I knew that about Corries with the sand. I asked about switching over to a sand subtrate a while ago. However I could not find any white play sand in my local Lowes or home depot. My LFS has crushed coral subtrate, I take it that is not the same as regular play sand?

I may wait till I can find some white play sand.

Odd, my local Home Depot and Lowes both have pallets of the stuff all the time. Odd that they'd be out.

No, you don't want the crushed coral. In fact you want no marine sand at all. It will drastically increase the hardness of your water and raise the pH.

They have was the dark tan color....I did not see any white sand, maybe I was not looking in the right spot...I can stop by again today....I smell a weekend project!!!!

Hmm well I got play sand at lowes and all that had was the tan stuff. So i dunno where to find the white stuff. Unless you try a pool store. Im not sure what color pool filter sand is or if you can get this time of year. And yes get cories lol...As you can see i have pandas...i love them!! Theyd made a great addition to your tank. Pandas stay on the small side...i couldnt find any dwarfs or pygmys but you might be able too!

i get white play sand for my turtles at home depot and/or walmart for pretty cheap

I'm new, i'm learning.... But I see you guys talking about white sand. Today from Home Depot I bought a "regular" bag of play sand. It's not white, nor does the bag indicate a color. Is this not acceptable? Is there a difference with white sand? I haven't opened what I just bought, so I can return it. But I like the tan color to "hide" the unpleasantries a little more. I'm aiming to get some corries too... I don't want to mess up.
