I have a male betta fish in a 10 gallon tank. I have 1 pond snail that I'm trying to get reproducing very quickly on purpose. The tank is filled with algae and I am welcoming a small "invasion" of these pond snails. When they're everywhere, I will release my assassin snails to keep them under control.
I have a sword plant that's just barely surviving because I had been using my bettas fish top (which had a great light) on my 10 gallon tank for my 3 hermit crabs. I had the tank in front of my bedroom window to help with photosynthesis. It didn't work. The plant began to die and lost a huge amount of foliage. I got a top for my hermit crabs now so the the top that has the light is back on my fish tank. I will get another plant (actually many) to help control the co2 in the tank and then I'll remove the fake plants completely.
Unfortunately, when I changed the substrate from the gravel I had to sand, I removed the pond snails so when I put the top back on,about 2-3 weeks later, I have an explosion of algae. It's even in my filter. I am unfortunately down to 1 pond snail who seems VERY happy now that I released him back into the tank. So, he's going crazy over the algae.
Now I'm waiting for him to start to take over that way I can release my assassins into the tank to keep that under control.
Now I'm left with 1 thing. All the fecal matter and other waste products left behind by a growing population.
I was going to add a clam or two to my tank but then I've read that they need a cool fast moving stream of water to survive and bettas can't survive in that. So, clams are out of the picture. Is there anything I can add to make the aquarium self sufficient?
I'm trying to make it so I don't have to change the water... ever. 10 gallons is too much to try to change every month. I think this is possible because it happens naturally. No one has to manually change the water in a lake, because the animals and plants that are in there take care of it all. I want to try to imitate this as best as possible.
I think betta fish behavior is unique depending on the betta fish, so let me give you an idea of my betta fishes attitude.
I heard that African Dwarf frogs are safe to add to a betta fish tank and they would get along. So I put 3 of them in with Freddy and he murdered every single one of them. So, I'm looking for something he is not going to kill. Is there such a thing that I can look for?
