I thought this would make an interesting topic. Lets talk about food kinds, feeding techniques, food brands and anything food related.
There are alot of things to feed fish and personally i think a mixture of foods is your best bet. I know a guy from my local reefing club that has been into saltwater for i think 60 years and has had his current tank for 40 something years! According to him back in the day the food selection was slim to none and he was pretty much stuck feeding flake. He claims his fish broke out with ich and disease all the time. He then started experimenting with other foods of more nutrition and the fish showed no health issues. He says his secret is the occasional fish roe, which are fish eggs. He carefully rinses them not to break any and feeds but does not do this often as they are very rich. Fish that naturally have alot of oils are best avoided but others make a great food source from time to time. Some fish markets and stores will give you the fish eggs for free when asked.
There are lots of different food sources.
Flakes, which i personally dont use. Pellets which ill drop in every once in awhile. All my fish, except the copperband ( that ive seen ) eat Hikari Tropical Marine-S, which i used only from time to time. Frozen foods are good foods IMO but they need to be pre-rinsed in tank or RO/DI water a few times until they water is clear and dont hold as much nutrition as live foods. Live foods are a good food source but need to be cultured or purchased and so forth. Home made foods are good too as you can regulate what goes in them and make them to fit your needs. Fish stores and supermarkets have alot of things for this and there are plenty of recipes on the web.
Personally when i feed, which is every 2-3 days give or take and certain things in between or longer i put a small amount of food into the water and shut off the pumps. I then go rinse and prepare whatever im going to feed. By the time i get back to the tank the corals have their mouths open
I then feed watching who is eating how much and then whatever food doesnt land on a coral i was going to feed, i use a arm glove and pipette to feed each one seperately. I usually use pre-rinsed frozen mysis which i blend some with selcon/garlic and add it to whole size mysis (which are still small) so its in different sizes. Frozen and live brine shrimp get used from time to time too, however their nutritional value isnt great. Live black worms are what my copperband loves along with mysis. I use small pieces of silverside/mysis/brine to feed the bubble tip anemone. I feel its important not to feed to much or to large of pieces as it will take more energy for the nem to digest its food then the energy it will recieve. Ultimately degrading its health. After about 30 minutes or so, or when the corals seem to be chewing with their mouths closed
I then turn on atleast 1 powerhead to blow any food that has reached the sand/rocks. Sometimes i will turn on both powerheads but usually leave the return pump to the sump off for the time being. I then monitor how much food is blowing around in the flow from the powerheads. If i feel alot of food is still in the tank i will net some out. The return pump gets plugged back in depending on the feeding. This is because it increase flow/could make the food overflow down to the sump/is connected to the skimmer, so it depends on what is being fed and so forth.
Garlic algae sheets (green and red) go in my tank every so often. I currently have no tangs or heavy algae eaters so this isnt overly important but i like to offer choices. The aglae gets eaten too. My flame angel, im sure snails, and ive seen my wrasse picking at the algae on the clip.
Just thought i would put some ideas out there. Thoughts?
