How many cories?

[Zorak]

I just bought two spotted cories and added them to my 25g guppy breeding tank. I didn't know much about cories when i got them except that they are peaceful. I really enjoy watching them swim around together and think i might want to add some more. What is a good number considering my tank size? Also will these guys eat algae?; or guppy fry?

5-6 is a good number. What kind of substrate do you have? They need small, rounded gravel or sand to prosper.

I have the common gravel found in my lfs; it is somewhat rounded and small... is this ok?

5-6 is a good number.

i'd like to have 5-6 but how many guppies can i have in there with them before its too crowded? I have 8 gupiies now +3fry

you should be fine if u have a total of 4 cory cats.

Cories should always be kept in groups of 5-6 or more, they really like company of their own kind. I think that number would be good for your tank. As for guppies, I'd say 12-15, depending on sex ratio (all males? all females? mixed?), assuming weekly water changes are taken care of and the filtration is decent.
