Well my name is Shane and I'm located in USA, I'm very new to the fish scene (at least keeping them as pets, plenty of experience fighting them in the wild ;P lol) but have been doing lots of research about fish and aquariums in my spare time. Looking forward to starting my first monster fish tank and would love any advice anyone has for a new aquarist like me! 
I'm pretty sure I have cycling a tank and setting up an aquarium down, only cause I have a crawfish currently in an approx. 14gal tank (this is my very first aquatic pet
) and since Ive gotten him (maybe a month?) hes molted twice and almost quadrupled in size (trying not brag, but hey, im a beginner and I cant say Im not a little proud LOL) Or it could just be im feeding him hikari carnivore pellets (filet mignon of the artificial food from what I understand.... ONLY THE BEST FOR MY BOY :,) ) But Ive done some waterchanges and siphoned his substrate and him seems to be a happy little camper. I also treat the water with a tetra solution I cant remember off the top of my head when I change the water. And Yes, youtube can be a great resource for quality instructional videos! Thanks for welcoming me and the advice!
