I'm looking at getting a 3g critter keeper and need some suggestions for a filter and heater. If you could give me suggestions that fit the following, I'd greatly appreciate it, but I'm open to anything, really.
For the filter, I need something that is: Quiet, low maintenance, and preferably under $15
For the heater, I just need it to be under $15 and, of course, functional.
Or if you can suggest a similarly sized set-up that is plastic, has a locking lid, and is under $20, that'd be great, too.
On a side note, I know it's not really in this topic, but my fish has fin rot, so I'm wondering, would it be better to treat him in the tank he's in now (it's a 4 gallon sterilite container with no other tank mates) and then move him to a new tank, or put him in a brand new, clean tank and worry about cleaning all the germies out once he's better?
