I'm saving up to start a 55 gallon aquarium in my kitchen, and I can't decide what to do with it. My two ideas are:
1. Try saltwater again but this time research more thoroughly and start a reef tank. Saltwater has always been so fascinating to me but when I tried it with a 10 gallon it went well for a little but in the end failed utterly. However, I do know what went wrong and could try to prevent it in this tank, but I'm a bit afraid of failure.
2. Combine the stocks from my 38 gallon and 20 gallon (they'd fit perfectly because they don't have too many fish) and after that use the leftover money to help fund my betta fish breeding project, turn my 38 gallon into a female betta sorority tank, and my 20 gallon either into a river tank or a shrimp tank. I think it'd be great for such changes and I'd love to be able to keep some of the fish I breed. And I've always been fascinated by river loaches and cherry shrimp and it'd be great to keep some.
And now I can't decide! So I need some help. What are the pros and cons of each, and which do you think sounds like a better idea? Thanks for any opinions.
