You're going to need more than a 6' tank if you want to keep a silver long term. If you can't afford proper housing, then you shouldn't be keeping the aro.
Try building a bricked pond in your living room...
Officially, tanks more than 4' must be declared and approved by HDB
But 6' tank is my limit, won't go any large like a 9' which a fully grown silver needs.
it's out of the question as it's a HDB.. Hmm I dunnoe how to make my mum to allow me to get a rubbermaid/or a large container .. She says people keep aros to look at it's scales and so on, but I think as long as my aros has more space to swim , im happy and it's alright if I can only look at it from the top.. Help anyone?
