Thanks for the heads up. I read on Planet Inverts the conditions needed to keep them. Fortunatly my tap water is spot on for them. Hard water and a ph of no less than 7.0. Most hobbyists set their Sulawesi tanks with a ph oh 8.0. Also the temperature should be atleast 78F. They have a tank to themselves (52litre) equipped with a sponge filter and also a fluval 2plus for a bit more filtration (intakes might be covered with nylon stocking).
