I recently bought a male betta. I am now the proud owner of one fish. That would not be big news for most people but it sort of is for me.
Fishkeeping has been a big hobby/obsession for me in the past. From about 1972 to about 2000 I pretty much had multiple aquariums going at any time. When I got married I had different priorities so I put the aquariums in storage.
I am working on setting up a fish room in my basement, but I have a lot of work to do before it is complete. In the meantime I have one fish.
He has made a little bubble nest in the corner of the tank. In nature, he would attract a female under it, where they would mate. The eggs would float up into the nest, and the male would care for them for a few days until the fry disperse.
For now, I have one fish. Red fish…
