A fish store near me has recently started carrying what they call Julii corys. I've completely fallen in love with them and want to add them to my tank! However, based on what I remember about the fish at the store, I think the so-called "juliis" actually looked like C. trilineatus
(now that I'm seeing pics online). Either way, I'm bound and determined to add a cute little shoal of these guys to my tank.
Here's what I've come to understand about them: I should get at least 4, though 6+ is better. They don't like bright light so they need lots of places to hide. They need a varied diet of wafers, pellets, bloodworms, etc. They prefer soft substrate, can't tolerate any changes in water parameters, and no salt should be used in the tank.
My tank is a 20 gallon high that's been running for three years with 5 harlequin rasboras and a male betta. (The betta has never picked on other fish before, but I'd of course keep a close on him. I'm prepared to move him to his own tank if needed.) Completely cycled. Substrate is fine sand. There's a mix of fake and live plants. No wood of any kind.
- Do corys like veggies (if so, what are their favorites)?
- Are C. julii and/or C. trilineatus easier or harder species to keep?
- Does my tank even have room for an adequately-sized group of corys? I'm worried about the amount of floor space a 20 high provides (24"x12").
- I've been using a little bit of aquarium salt in my tank. How many water changes do I need to do before salt is removed and corydoras will be safe? Is there anything else I need to do to make sure all salt is removed?
- Anything else I should know about how to care for corys?
Please and thank you, everyone!
