Ok now that I got you here I am going to try to help you, but I think I am going to tell you what you did not want to hear. That said here is the way it will go down (if not right away not to far in the future).
1. You have 2 fish that are in a 12 inch deep tank that both will outgrow within about a year. If you feed the Pork well it will get from 6 to 12 inches. You have the same problem with the Trigger altho they do not grow as fast. At some point you will need to get rid of one or buy a bigger tank.
2. Once the Pork begins to eat (it can take from 2 days to 2 weeks depending on the fish and how it likes its new home and tankmates) you are going to find it and the Trigger will begin to fight over the food as they are both very aggressive eaters and they are in a very narrow tank. Your only hope is to feed at both ends of the tank and try to keep them apart during feeding.
3. I am not a advocate of Triggers with Porks but do not feel bad everyone seems to want to do it (and yes it can be done but in a very large tank decorated just right for both the fish). If Grouperhead sees this post he is going to ask me to tell my story about Triggers and Porks but even I am getting bored with that story cause I always have to tell it after the fact.
4. Porks are lovely fish and believe me many people walk in a store and out with one because they are hard to resist. I blame lfs for not being more forthright about the proper care and needs for this fish tho. They will tell you it eats like a pig, is hardy as heck, and sociable, and they are lieing thru their teeth because the only true part is the first one.
5. Now that you have one if you want to know more about them, their care, their needs etc click on my homepage and go to the info there on Puffers.
