Fish Crazy
50% is top amount. I do it in 2 changes. Like i take 25%, refill, then take out 25% again and refill.
For a 15 gallon, i think you could have 6 or 7 corys tops.
I have five at the moment so that would mean 2 more....aaahh....would love so many more
You could get 6 of a species of corydoras (possible more, but im not sure how much) I dont recommend Panda Corys because they are sensitive, and just not a good beginner cory. basically all cories are the same though, take good care of them and they will be your favorite fish.
They do need to be in shoals though, 4 or more, preferably 6 or more

Do they have to be all of the same species or will different species shoal together??
Panda's are lovely though aren't they
