Hey, I have my betta fish in a 5 gallon tank with quite a few live plants (though all rather small) and recently the tank has been accumulating a lot of algae. I wouldn't be concerned but the algae is growing all over the plants and I'm afraid if I don't clean them off every few days they're not going to get enough light to survive. Plus, they look kinda gross with all that algae all over 'em. I figure the bioload in my tank is pretty high considering I need to add fertilizer to keep the plants alive. I was thinking about getting one or two otos to put in the tank but I had a couple of questions.
- How many can I keep in the tank being that I have a filter and the tank is cycled and heated (though usually around 82...college dorm heat)? Would this be enough of them to keep them happy?
- Would they coexist peacefully with my betta fish? I've never had any other fish in the tank with him and I'm not sure how to handle the situation if they don't get along.
- Is there a better alternative? I had been thinking shrimp but I'm afraid my tank would boil them.
