Enough Room?

[Chrs]

Right now I have a 20 gallon set up in my room that has 3 guppies and 4 peppered cories, and I'm planning on adding 2 Bolivian rams(M&F) in about 3 weeks. I was wondering if i would have enough room for a BN. If there is what would I need to add to my tank(I'm 13 so my tanks not amazing), I was thinking maybe a PVC cave.(I already have one piece of driftwood that's about 8 inches tall and 6 inches wide). I just spent about 2 hours researching and I read that there are different types of BN's?!?!? Is this true? Some people said that there's get to be about 8 inches but most places say they get to be 4-5 inches long. Which size is right?

You should have ample room for a BN there I'd probibly add it a week or two before the rams though, they are heavy waste producers so cannot go in at the same time, and the rams will benefit from a more mature tank

There are several types of BN. Some of the more fancy ones, like the starlight BN, will get to between 6 and 8 inches, but most of your run of the mill BN's stay arround 4-5, depending on the exact species. I'll assume you are shopping on a budget, and will be getting a "run of the mill" specimin, in wich case you sould plan for a 5" specimin, but they usually stay smaller than that IME
