I just recently purchased a ten gallon tank for my betta. I plan on letting it cycle for a few weeks and then possibly adding a few other fish. I've been doing some research and it looks like I may be able to let the betta coexist peacefully with some other types of fish. Anyways, now I'm going to have some fun trying to figure out what combinations I could add to my little ten gallon. I figure that should trouble arise between the betta and anything else, I could put him in my original 2.5 gallon tank. I've read that cory cats usually do well with bettas. My tank is planted and I will be adding more/growing more during the weeks that the tank cycles. I also have a filter that is rated for up to 15 gallon tanks, but I may go back to the store tomorrow and get one rated for 10-20 gallons (The one I bought today was cracked). What else would be compatible and how many? I don't want to overstock the tank and I want to get things that will get along. I had my eye on some dalmation mollies, but can't find any info as to how big they get. Most websites say they get along well with bettas and a few say they nip fins. If I got a cory, would I need more than one? Also, what type would be most compatible? I also read about kuhli loaches and those are pretty neat. My room mate just got one for her ten gallon. The lady at petsmart said they should be in groups of more than one also, so I'm not so sure about them either. They also like to hide it seems. What else and in what combinations could I put in my ten gallon? As I mentioned before, should it not work out with the betta in a community tank, I can definitely separate him into another tank. I just don't want his tail to be nipped and I don't want any injuries! Also, how long should I wait for the tank to be cycled? I've always heard two weeks, but some websites say 6-8 weeks. I have access to already cycled gravel - could I put some of that in the tank to help out? Once the tank is cycled, how often should I do partial water changes and how much? Thanks so much! This is my first time setting up a ten gallon tank, so I want to do it right. I've only ever had 2.5 gal. betta tanks.
