This is a discussion on Do I Have Space For More Fish? within the Beginner Freshwater Aquarium forums, part of the Freshwater Fish and Aquariums category; -->
I have a 90 litre(23 gallon) tank. Currently, I have it stocked as follows:
- 4 Mollies
- 3 guppies
- 2 swordtails
I would suggest that you are at the limit in terms of space; fish like room to swim and 11 fish that attain 2+ inches in a 23g doesn't leave much room. I didn't include the corys since they are mainly on the substrate. I would however suggest a couple more corys, they are shoaling fish that need to be in groups and 2 is not sufficient, 3 minimum but you have space for 4 or 5 in total (assuming they are not the larger species).
