I am going to purchase a betta fish. I have a 20 litre tank, and I'm in the process of cycling. I have driftwood and live plants too.
Anyways, while at the petstore, an employee told me I could keep a bristlenose with a betta, in my 20 litre, and that she does in similar conditions.
I really liked the idea, but when I went home and started researching....problems started appearing. From what I can tell, bristlenose pleco's need to be keep in a tank thats 75+ litres, and this seems excessively high to me, even in a community tank scenario. Is this right? Could I put a bristlenose in with a betta?
