Cory's and Schooling
I have a small 15 gallon tank. with the following lovely's in it:
1 Mystery Snail
1 Albino I have had about a year now
1 Panda and 1 Greenish/Grayish/ Blueish one I got at the same time about 2 weeks ago.
and a single Loach, he is slithery and brown.
I would like to add a few more fish and was thinking a Male Betta might make a visually pleasing addition as the tank is in my office at work and gets plenty of looky-loos.
But I recently was told that Cory's need to be kept in groups of 6 or more. My Panda and Albino are fairly active and will rest together at times.
The Loach and the other Cory like to share the same hiding spot, but I think it is just because they are both shy.
The Albino had been on his own in a Goldfish tank for a year now seemed to thrive. But we recently rehomed the Goldies due to their size and "Al" seemed to be very lonely and depressed.
He does seem to tolerate the panda more than seek him out, but they both seem to be doing well.
I am more worried about adding to the school and someone being pushed away.
I was told that mixing the Cory's would be fine and they will form a school, but I am doubting that advise (pet shop advise...) Should I get a few more of the Green/Gray guys to keep him company? Or do you think simply adding 1 more of each to keep the diversity will work?
It's a 15 Gallon Tank and I am hoping that 6 Cory's the Loach, Snail and Betta won't over crowd them.
