Hi, I'm trying to advance my knowledge about keeping a betta fish. I have gone without a filter since I got my betta in August 2016. I've been getting by on just doing (mostly just partial) water changes every 2-3 days per week, and adding conditioners, removing uneaten food/waste, and overall monitoring my betta. I have been reading about how filters are pretty much a necessity for a betta fish, so I broke down and started researching filters for a good compact sized one for my 2.7 gallon, and found the azoo palm filter, ordered it, and now I have it. However, I am not sure how exactly to go about installation in his tank? The instructions are short and don't say much. He already is in there and was wondering if I can just place it into the tank. I am not really looking to keep buying more accessories for his tank (financial reasons mainly) and so hoping everything that comes with this filter will hold up until I can get something supposedly better. If you have any expertise on the installation of a filter in an already inhabited betta tank, please let me know. I would like to get this done asap so he can have cleaner water and I can perform less frequent water changes. Thanks alot!
