So I broke the cardinal rule of aquarium keeping and let Aquatic Environments talk me in to buying a chalk basslet for my 10 gal nano. I had never looked at them and upon returning I did my research and found that the min tank size recommended is 20 to 30 gal. What should I do. The only other fish going in this tank is a green clown goby. There is about 10# lr in the tank and plenty of room to swim around. I love the lok of the fish but I don't want to be cruel to him either. What do you think??? And I know I am kicking myself for buying something with out researching it first.
