How many Cory Cats are suggested for a community tank?

Question

I currently own a 20 gallon freshwater tank. I haven't gotten around to setting it up yet because I've been doing alot of research online about aquariums. I plan to use live plants and a school of Tetra fish (neons) to start with. I have read that Cory Cats are good "bottom feeders" but how many do you suggest I add to my tank? Two? Three? Do I buy one male and two females? Thanks in advance for your input.

Answer 1

Actually, Cory's are schooling fish,and group spawners. To fully enjoy these little beauties 6 or more would be a good start. I'd select one of the smaller species and skew the population to females,but more that one male should be included. Both the tetras and the Corys are very sensitive to ammonia,so be very sure the tank is well cycled before adding any fish. This will take some time, but is the safest and most humane way to start an aquarium.
Your Corys will appreciate some vegetable matter in their diets and that is the best way to condition them to spawn.

Answer 2

for a 20 you'll want to do at least 3, you never mention what kind you want. some stay under an inch some get over 4. if i may make a suggestion get the panda cory. one of the smallest and best looking in my opinion.
you dont want to start with neons as they are rather fragile. i know they are usually only a buck bet please trust me, start with some kind of danio. pearls or zebras are the most common.

Answer 3

Nope. Blue and kissing gourami grow to be somewhat great and aggressive, like consume neon tetra great, and kill one yet another aggressive. So do angelfish - they have an inclination to consume guppies and neons. you will possibly desire to save dwarf or pearl gourami in that tank (with those tankmates). they are smaller and much less aggressive. Ian 25% water transformations might desire to be each week for a very stocked tank (to regulate the nitrate point) in case you basically save some fish then much less water transformations would be ok

Answer 4

Usually 3, but they don't always have to be in schools. They are alright alone, but it's usually good if these cute little bottem feeders have friends. It's neat to watch these guys school, for I have four (3 albinos and 1 leopard). These fish are also easy to breed and it doesn't really matter what genders you get together.

Answer 5

Buy 2, probably a male and female but it doesnt really matter.


Then you want 15 neon tetras

I also suggest getting 5 danios to start off the "cycle" process.

Add the danios and then add the cory cats about 2 weeks later, then a week after add the tetras.


"Cycling" with fish is so much easier and faster

But i will probably get thumbs down for saying this. You can do a fishless cycle but it takes ages

Answer 6

for a 20 gal about 6 they like to be in groups. male and female doesnt matter but they may breed in yyour tank if conditions are right but i wouldnt worry about that. dont buy 6 at once get 3 today then maybe 3 next week.

Answer 7

I agree, not only are they most natural in groups, but you'll find them braver and more active this way. In a 20 gallon tank 6 is certainly no problem, and a few more is more then possible.

Answer 8

I think 3 with 2 females

Answer 9

get 4-6 corys and make sure you specifically feed them. don't just depend on them to live off the leftovers that the tetras fail to get.
