Sorry Stacy. I have kept neon tetras for ten years and have NEVER had any fin nippers. Do they occasionally attack fry? Yes. But they have not nipped fins. Khulii loaches do not school. They mostly keep to themselves, occasionally following one or two others. I had a ten year old dojo loach who lived without any other loaches for his entire life. He thrived. Got longer than any I have ever seen, was fat and healthy, and was quite annoyed by my worm loach following him. Cardinal tetras can be kept in groups as small as three, as can Neons. Cory cats do not need large groups. Two together are fine. Mine lived and thrived for many years this way and were shy to other fish. Some of what you posted is simply not true. My Bettas are in fish bowls, although large ones, with frequent water changes and cycling into different bowls each cleaning, they have done great and my male is building a bubble nest already. You mustn't always jump to conclusions. Not all bowls are oppressing environments. My fish much preferred the bowls to my pond and 18 gallon, where they were scared, insecure, and sticking to the plants to avoid being out in the open. The space was too vast for them. You're post was a little harsh towards Dianacatz. You never know if you are dealing with a minor, or a very juvenile adult.
