cory cat qustion

I am thinking of getting a school of cory cats for my 55 gallon, I am thinking 6 or 8.

I have some questions about them since I have kept them before.

My ph is 7.6, everything I have been reading says they need a ph of 7 so wondering if this could still work?
What should I look for at the lfs as far as picking a healthy school of them? Is there anything in particular I should be looking out for disease wise with this fish?
Temp is 76, water is hard, lots of live plants/driftwood and sand substrate. They will be housed with 2 guppies, 5 ghost shrimp and 7 monty swords (who I am hoping to get fry from eventually)

Will they eat fry?
Will they eat ghost shrimp?

Will they disturb and dig in the sand substrate?

Are all the varieties wild or are there certain colors that would be considered the "wild" version, since I have mostly wild fish in this tank I would like to try and get the natural colored cory cats and I am not sure what that is.

TIA

I wouldn't worry about the Ph.
My Ph is the same as yours, 7.6 - 7.8,

Some of my tanks have lower ph due to different elements being added,
I toss my cories between tanks all the time, I find they are so easy and versatile,

I swear they are one of the easiest fish to spawn, I have several tanks now holding hundreds of babies,

I also have a Ph of about 7.6 and my cories have done very well (although I do have moderately soft water).

As far as picking out healthy cories at the store...just observe them for a while and look for active cories with their fins up. If their fins are clamped there is likely something wrong. Also, make sure their barbels (whiskers) are nice and long and aren't worn down or show any signs of infection.

Don't know if they'll eat fry. Mine never bothered the ghost shrimp. Sand is the preferred substrate for them. They will snuff around in it but not enough to really move the sand around.

There are many many different types of cories. Many LFS will order them for you also. Planetcatfish.com is a good reference for the different types of cories. Here's a link. Look under the Corydoras name.

great thanks!

omg there are so many but I think I am going to get some common ones the pet store will have.

The tank just needs something more to make it complete and I think these guys will be the perfect addition.... still deciding on 6 or 8, it would be great if I could find a dwarf species but I don't know how common they are. I know I have seen peppered and panda cories in the local store but beyond that I haven't really looked that closely at them.

I am excited to add something new and have heard these guys are quite fun to watch.

I tried some cherry shrimp (figuring that they were about the size of ghost shrimp which my fish are fine with) but it was a total blood bath....... I felt so bad but my fish are tiny (about an inch) but they were ganging up on the poor shrimp. But they don't bother the ghost shrimp and I am sure a cory would be totally fine.

My tank seems kind of empty now with only 9 small fish so this will be exciting.

Many of the Corydoras species you are more likely to encounter are included in our fish profiles; the second tab from the left in the blue bar across the top takes you to the profiles, and they are obviously under the Catfish section.

Many are tank raised and will do fine in your water. In the profile of each species it mentioned ideal water parameters. Those that are wild caught can be more sensitive.

Corys will very readily eat eggs or very small fry if they find them. Livebearer fry tend to remain near the surface among floating plants, so this is less likely. But my corys regularly eat the eggs of my Bolivian Rams, or if they should hatch, they will gobble up the fry if they stumble across the shoal. Most all fish will eat eggs or fry if they can fit them in their mouths; it is natural fish food. As are shrimp or any freshwater crustacean--again if they are small enough.

One other thing to watch for in the store tank, are corys that are lethargic. Not a good sign, as lethargy and rapid breathing indicates high stress. Depending what is causing it, they may or may not recover.

Thanks byron

the ghost shrimp seem to handle themselves, even with the amecas who slaughtered 10 cherry shrimp I bought the other day (was testing with the ghost shrimp to see if I could do cherry shrimp and obviously I cant lol)

So I think they will be a good fit, I just don't have experience with them but I guess there is only one way to gain that .

I picked up 5 peppered cories today.

I noticed when they got one that one doesn't have barbs... is that normal or something I should be worried about.

Originally thought to be caused by an inappropriate substrate, it's now known that barb damage is caused by stress or malnutrition. Keep an eye on the cory. Take him back and exchange him if you can.

There's a pretty good chance he'll recover as long as you don't see any other symptoms... One of the problems with cories is that they're sensitive and hard to medicate if you must.

I agree with redchigh on the cause. I wouldn't myself return him, that is stressing the poor fish unmercifully. Loss of barbels in no way affects the fish as far as I have read; and I have had some without barbels and they live for years and eat fine. Corydoras sterbai seem particularly prone to barbel degeneration, not sure why.
