Just a little PSA: Don’t buy a goldfish!
They are not cute lil fish bowl guys. They are domesticated koi. They grow a foot long. Their water parameters are not compatible with anything else at the pet store. They will poison their tank mates and themselves with their waste and will choke to death on any survivors. They live as long as a cat or dog, if they actually have suitable conditions.
Speaking as someone who now has to find a suitable pond after taking in a tank left behind by a neighbor kid who’s off to college, your 20-gallon breeder tank isn’t going to hack it. And if you think it’s fine because that pleco’s going to keep the tank clean… I give you a very bombastic side-eye as I wander off in search of TWO ponds.
