I didnt say they will be in here indefinately? I have 7 tanks, this is the 8th. I am not unhappy with peoples advice but it seems to be inappropraite preaching.
You wanted the tank to enhance a dull area of your living room. Sounds like you plan to keep it there permanently. And we are advising you, like you asked, not preaching.
Ok, wait. Are you saying its a 19 litre tank or a 19 gallon long tank?
The tank wont move, the fish can. There are clearly two schools of thought in fish keeping. Me and everyone else who has replied so far are int he other one.
