I managed to stupidly shatter my heater last night doing a water change when I pulled out the wrong plug and didnt turn it off. Im looking at what to replace it with and may go with a hydor external instead of an internal and my questions are;
will my fish be ok with the colder water whch is currently sitting around 21 - 22 degrees (usually 25-26). the tank is in a centrally heated lounge and the fish are Blue tetras and high spot rasporas.
Also I was planning on getting a tetratec ex1200 and currenly has a sera 900 which has 12mm tubing. has the tetra got the bugger 16mm? (ie if I buy the 12mm hydor heater will it work on the ex 1200?)
thanks Stu
