I just got a new fish named Eugene about 3 days ago (a metallic green and silver super delta). I have an Aqueon Minibow 2.5. I have a Marina heater installed and the tank came with a filter. The problem with it is that the outflow pushes down my betta fish. I've tried baffling the filter using the plastic water bottle method, but I'm afraid Eugene will tear his fins on it since his fins are very long. I've turned it off and have been trying to purchase a TOM Mini Internal Filter. The problem is that I can't find anyone who sells it in Canada. Petsmart stopped selling them online and they're only available on amazon.com (USA) and can't be shipped here.
I really want to get a filter so I won't have to do as many water changes and so the heat can be evenly distributed throughout his tank.
Does anyone know a reliable
shop where I can purchase the TOM Mini Internal Filter in Canada
? And how much and how often should I change his water now that his filter is turned off?
