Thanks for your reply..Welcome kishor. I am originally from india, living in Bay Area for past 10 years.
It will be hard to source corals as well as getting online details since it is banned. Start with FOWLR /fish only system and let the rockscape age. I know a few with salt water tanks and i have seen gsp and probably some euphylias in Kolkata, pet shops back in 2014. I highly doubt anything like that present today. Let us know your plans and any questions you may have. Equipment and rest (salt etc) are scarce but definitely sourcable, because of the niche saltwater tank community there.
Surely its hard to source corals here. But its not impossible .. Especially if I could get frags from other hobbyists. And I have seen few pics / posts of Indian hobbyists keeping all kinds of corals!! So, I'm hopeful about it!!
