Hello and welcome to Rescreatu :D
Glad to hear you keep coming back
Many people here are on similar sites too but Rescreatu is the one everyone has stuck with over the years xD
Fist piece of advice I can think to give:
Check out the rules, if you haven't already!
They can be found im this link
http://www.rescreatu.com/rules.php
and below your logout button.
Ranchers rely alot on luck to get by so it's hard to give much advice but here we go :D :
Use the Creatu search to check pet prices so they are fair and affordable, never be afraid to ask for hep either :D
(If you want I'll Rmail you a guide for setting up the Creatu search to make checking prices and looking for pets easier?)
Selling your hatches are a good way to get a steady amount of TU too, hatches usually sell for 100-150k each.
To sell hatches:
The buyer sends you eggs and Tu, you hatch the eggs and tell them the result.
the buyer then tells you if they want to keep the pets and if so, what to name them.
You, as the seller, then name the pets what the buyer requested and send the pet to them :D
Pets with nice names sell for more, real word names and real names can go for millions of TU. Though you will be lucky to find a nice real word/ real name that is free to use its worth keeping this in mind.
Avoid naming pets things like : sdrft986
and avoid using numbers in names.
These are a few, I hope they help!
If you have any questions don't be afraid to ask ^u^
