Yeah there are about 7 more tanks you cant see in the pic and 5 1g containers with a fish, so Im lucky the wife is good about it. I want more space but she isn't budging on that so I must be even more creative or kick a kid outta the house
the key to keeping cost down is looking for good deals on 2nd hand aquarium stuff many tanks were free, the most paid for any tank was 25 bucks and often included heaters, filters and décor. Lots of power cleaning involved but well worth it. Water change day can be lots of work.
