once again you are not reading what i posted. My fish that i care for are fine. I do weekly water changes on ALL six sumps including saltwater, that is WEEKLY. each sump is about 300 gallons. My nitrates, nitrites, and ammonia levels always r at 0 and that is checked EVERYDAY. When i said i am an aquatics specialist i was merely listing my position in this company. The reason i leave seaweed in the tanks 24/7 is to reduce deaths by hunger either by damsels or other fish i do not have green algae growing anywhere in my tanks i am referring to sheets of seaweed i am sure you know what those are. My PH on the saltwater tanks are 8.3-8.4 and the salinity ranges from 1.023-1.025 but i keep it mostly between 1.023-1.024. There is a protein skimmer as well. Everyone is fine, the fish are surviving, especially now since i took over. I have fish i have been keeping for over a month that are still alive, and well. My anemones r thriving and i feed them weekly with silver sides. I also change the poly fibers in the filter weekly due to wastes. The water is fine, even though it evaporates quite quickly. I am there 5 times a week, and when i am not, there is someone that does the basics like feeding and water testing. MY PROBLEM IS that i want to know creative ways to make tangs eat MORE, i want to fatten them up. The reason i am unsuccessful is because there r a few things working against me such as: they hide when i want to feed them pellets, seem unresponsive to live food which ends up dying, ignore frozen thawed foods, and could care less about anything else. I have contacted the people who ship us these fish to ask what they feed them there but have not gathered helpful information. I also asked whether these fish are tank raised since it makes a difference. Our store is trying to provide the best care for their aquatics department that's why they hired me, and since they have hired me the fish have been doing much better, and surviving. I also tell the staff on days i am not there to watch out for possible problems and do what is on the maintenance schedule for that day. I ASSURE YOU THE FISH ARE WELL TAKEN CARE OF, THE TANGS HAVE BEEN IN MY STORE FOR ALMOST A MONTH IF THEY WERE NOT EATING AT ALL THEY WOULD HAVE DIED BY NOW. What i want to know, again, is creative ideas on how to get them to eat MORE, and hopefully become more extrovert. that is all the information i need from you. And also like i said before i don't need basic information, or any information i can get from a book, i know or have those resources readily available to me. The people i usually consult with and i have never had this problem with tangs before therefore i am looking for more information here. If you are not going to write specifically about what i am asking, why even write about anything at all. instead of making inferences about the way the fish are treated or the condition of the store or where they are kept ask for next time because you obviously don't know every detail about my tanks. And you might not have meant to "hurt my feelings" but you were trying to, well i think i don't have to explain myself. I still need an answer, if not from you, from whoever that ACTUALLY wants to help not assume what i do and don't do, or belittle me. I am a responsible person, and that is why i am here to ask for ideas, i work hand in hand with my manager so he knows exactly what is going on and so does the district aquatics manager that stops by or calls regularly. The manager also does most of the maintenance on my days off, i have posted water conditions with accurate numbers at least twice but for some reason you read straight over those so i am putting them on here again. I do not feel "horrible about myself" in fact i am very proud of my work and have been complimented several times by my peers on how good things are doing. I do not need another conscience, i have one that has worked great so far in my life. I also have been building close relationship with my customers, and would never sell them something that wasn't good or doing poorly. Furthermore i usually request them bring me a water sample for testing if they haven't gotten one done lately or have a kit at home for both fresh and specially salt water. If i am unsure about a good home for the fish i can deny the sale or if the water test came out with bad results i won't sell either. Of course i test the water before i add salt all our sumps use the same water that comes out filtered, that is a no brainier. Phosphates however, out company does not carry tests, strips, or awareness it even exits. I am being forced to go corporate on the matter because it's so important. We are too low of an assortment store to carry coral, all we have is fish, live rock, anemones, and cleaning crew. Copper treatments in the store or products and forbidden by petco therefore our tanks are copper free, and we have no quarantine tanks at the moment but i am working with management to make arrangements. Any other information you need ASK and i will answer do not make assumptions and by all means read ALL of my post. The fish themselves are clear, or pristine, they r not cloudy or discolored, no funguses, no pop eye, not body or tail rot, no missing tails, or nipped fins. thanks
