cycled tank

Sorry in advance if I placed this under the wrong category I noticed that Drogon's pectoral fins have been getting smaller and what looks like some sort of dark build up around the edges (suspecting mild fin rot), so I'm considering adding some bettafix to his 10 gal. The thing is, it's a...

I recently got a new betta about 2 months ago. He is in a 5 gallon tank with a heater and filter. After about 2 weeks of getting him, my small 5 gallon tank recycled, causing nitrites to spike. Around this same time, I noticed my bettas fins starting to appear ripped. I suspected fin rot...

After I have cycled my tank, how should I clean it? I know how to do water changes...but I've read that washing decorations can disrupt the cycled tank. I can't just leave them to get dirty...?

Ammonia reads close to 0 (just slightly over? Not good at telling the color of the ammonia test), nitrites are definitely 0, and nitrates are between 0 and 5. The tank is divided, was formerly getting a partial change weekly and 100% change each month, and is filtered and heated. I was not...

I currently have 3 bettas that are in heated 3 gallon tanks each and I keep up with water changes and such. for a long time I've wanted to get filters and cycle their tanks. I know since I have fish already I have to do the "fish-in" method but I really don't want to do that. I don't want to...

I plan to use a 60 liter tank for breeding my Betta's and I want to know if I can quicken the water cycle by taking some pond water from my area and putting into my tank or could I just soak my sponges in them?

I currently keep my beta fish with two goldfish and a pleco. He hasn't been looking all that good so I started looking on the internet and now realize that he needs warmer water and less water flow and surface action than the goldfish. I feel terrible for my ignorance!! I want to move him to a...
