    Identifying what this is

    (Sorry if it's bad quality, there's algae on the walls. But that's not the main point I want to discuss.) There is this brown ball floating in my fish tank. It's not sitting on the decor; it's floating in the middle of the water. I have no idea what it is. The last time I added anything new to...

    Freshwater Catfish ID

    I recently bought a small catfish from Petsmart that was mistakenly put in with the otocinclus. I have no idea what it is even after searching through google. It mostly hides until the food comes out. It’s a voracious eater and has already grown a good amount. Any help would be greatly...

    How to cure Ich without killing beneficial bacteria

    Hi everyone, I have a case of ich in my tank. Just wondering what the best treatment for it would be. I have melafix and Pimafix, but I’m wondering if those are strong enough. I’m also nervous about killing off my beneficial bacteria because I don’t want to have to cycle my tank again. Also...

    Hi, I was just wondering if you have to plant Anacharis or if I can leave it floating. I don’t have enough substrate at the bottom to plant it right now, it’ll just float up. Should I get more substrate and plant it? Thanks!

    What is wrong with my Oscar?

    s/he has been acting strange lately, something is obviously wrong but I can’t figure it out. We’ve tried dosing the tank with Melafix, salt, general cure, but nothing seems to work. S/he is about 1 1/2 years old and is getting progressively worse. All other fish in the tank are in good health...

    Why is my (soft) tap water becoming hard in the tank?

    New to this and new tank - after weeks of prep, finally have neon tetras in. Testing the water, all seems fine except for the water hardness, which is measuring at the hardest on the scale (180). We tested our tap water and this had a very soft measurement (20). We now have a new tank filter...

    Hello, I'm starting up my tank again with now 3 male guppies in an 18g tank. It is about 18inches tall, 17inches wide and 14inches from the back to front of the tank. I was thinking about getting glofish. Would they get along with the guppies? Or any other suggestions
