Okay, so I've only ever had a few fish and that was waaaaayyy back. I have 10gallon tank that I just set up last week and put a male crowntail betta in this Monday. I have an old heater, air pump, and light my uncle gave me. I cleaned the tank, washed the gravel, diy-ed a filter (I did research ideas on that and found one i was capable of doing and supposedly works, although once I have enough money I plan on getting a proper one), dechlorinated the water, and left it running for about 4~6 days. I also tested the water levels with a 5-in-one test strip before adding the fish. I just recently (tonight) read that I was supposed to cycle the tank. I'd like to eventually add another few small fish or a couple of snails as well, mainly to help with waste and such. What do I do? Do I go ahead and cycle it with the betta in the tank or do I remove him and cycle it? Or for that matter, is it sort of cycling now and I need to start doing water changes and daily testing? Oh! And I do have a spare 2 gallon that has a filter (needs a cartridge but thats easy to fix) if it is needed. Edit: I just found out today that my 10 gallon is actually a 5.5 gallon, I have no idea how I didn't realize this before. When it was bought I remember being told it was a 10 but here recently I've noticed it wasnt much bigger than my 2, so I measured it and realized it's only a 5.5. Anywho, today I acquired a proper filter, an ammonia test kit, and a bottle of API Quickstart. Tomorrow I'll be redoing my tank and starting the cycle. Thanks for all the help, and any other tips y'all might feel like throwin' out are still greatly appreciated.
