I have a Betta in a 17 gallon tank. This is my first time owning a tank and when I bought the Betta with a bunch of other fish I had no idea what I was buying other than that is was very pretty. I had asked the guy in the fish store to warn me of incompatibilities, boy he must have been laughing as I went back again and again as my Betta killed 21 other fish over the next couple of months. Being new to it all I had assumed my tank was at fault and kept on buying in batches of 5 until a friend said 'do you realise you have a Japanese Fighting Fish in there?'.
It is a gorgeous fish though and I can't bear to part with it, its genocidal tendencies apart
Big tank though for a single fish. I really would like to add more but want to know what. I read that Neon Tetras work well if you buy a sufficient amount of them. Not really interested in non fish solutions such as shrimp.
Any help would be much appreciated!
