Sawadee krap.

Many thanks for your input.
GF certainly interest me.
1.Have to read up more on GF breeding but is the waking up at 4-5 am a daily affair all year round?
2.I'll be renovating my place and would like to include pond construction.
What's the acceptable depth for most fishes [ especially when nil specific species is decided yet ]?
3. What species is low maintenance and could reap some money by selling their babies, please?
4. Have idea of keeping small arrowanas and selling them when they grow bigger, is this advisable, please?

Very best regards.
