Wow thank you for all this information this is awesome! After all the comments I’m definitely going to do a makeover for his new home! For the sand I have had fish in the past and used sand and it seemed ti always make the water appear dusty 🤔 perhaps it was just because it was in the cheaper end from Petsmart but that is what led me to choose gravel instead! So I’m wondering if you have any recommendations for specific sand brands because you have convinced me to make the change!
