Cory Cat Substrate

Hi Everyone!

I am thinking about getting some cory cats in my 10 gallon. Right now, I have a gravel substrate. One person on a different forum had the same gravel and said her cories were fine, and I really don't want to have to change my substrate, so what do you guys think? I have this gravel:

Petco Dark Blue Aquarium Gravel at PETCO

Would this be OK for the Cory Cats?

Thanks!

I have my cories on sand, which they love to dig through and root around in. Not sure how they'd do that with gravel. It's not sharp, but I'd still worry about their barbels getting worn off.

14g Tall:
Planted, eco-complete, Red Cherry Shrimp

16g Aqueon Bowfront:
Planted, eco-complete, 8 Ember tetras, 7 Green neon tetras, 6 Harlequin Rasboras

36 Aqueon Bowfront: Planted, sand, 10 Julii cories, 8 Zebra Danios
7 Cherry Barbs, Asst snails & Ghost shrimp

I am also growing a carpet of plants. Will this help protect them?

I have to think not, but mostly because they really like to get into the substrate, even filtering the sand through their gills. It's a riot to watch them snuffling around. They do like plants, though! Mine lay around on the sword leaves like they're little fishy hammocks.

What other fish do you have in your tank?

I am doing a fishless cycle right now. I am going to have a betta (with A TON of caution, I know), a zebra nerite snail, and some shrimp. If I end up having to change my substrate, how could I do this?

What kind of cory cats?

Most cories get too big to be in a 10 gallon, especially since they really do best when in schools of at least 5. That's just too much for a 10 gallon to really handle :/

Just scoop out all the gravel and replace it with sand. At this stage, you'd be in good shape for that. Play sand like you get at Home Depot or Lowe's works great. It just needs a lot of washing.

And yes, I agree that a 10 gallon is a little small for cories, but I could see doing a group of 3-5 of the smaller, dwarf varieties. Cories definitely like to be in groups. Mine lay in a big pile sometimes, all over each other. They're one of my favorite fish of all time.

Is there anyway you could upgrade to a larger tank? Even a 20 gallon long would open up the number of fish you could keep and make happy.

I am planning on the Corydora Hastatus or Habrosus. I am thinking a group of four. I cannot upgrade, because I will be going to school and will have to be able to move the tank. How much will it mess up my cycle if I change to sand? How deep should I make the sand (I currently have 1 inch of dirt on the bottom and 1 inch of gravel for the top)?

I don't think it'll mess up your cycle too much. Besides, with plants you don't really need to cycle as much - the plants really help soak up all the fish waste and convert it. I don't know about dirt and sand. I just have sand. Maybe someone else can chime in on that.

Agreed. if you can't even keep a minimum because the tank is too small, you should wait to get them until you have a larger tank. Sacrificing the school size to make them "fit" is not responsible fish keeping, IMO.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta
