So I have a 10g set up with 6 harlequin rasboras. I'm still deciding on what to put as my final fish. I was thinking on maybe going for 1 GBR. The 10g has 2" of substrate, but. Might remove some just for the extra water, and then going for hardier plants like anubias, java moss, etc. I already have DW in the tank, but the ph remains higher at 7.2. So I was thinking of perhaps adding tons of java moss which I have growing in a different tank, and adding Indian almond leaves to make the water more acidic, or perhaps peat moss. My question is, would a gbr do fine in a 10g? I know most people say minimum is 20g, and 30g is recommended...but wouldn't it be better if it's say in something resembling it's natural habitat than in a 20 gallon that doesn't have plants and is crystal clear? If it's a definite no, which I'm guessing is the case, could it be temporary until I clean up my 20g and move some things around? How long? Like a couple months, a year? If I remember correctly gbr only live for 2 years...
