That's so funny that none of mine will touch bananas! Lately our bananas are not very tasty, so I wonder if that affects it. Your bananas are probably yummy.

I switched to organic bagged bananas here in IL and the taste is so much better. No idea why but I won't go back!

cool...but can i ask that maybe someone starts a thread on what we can actually feed our little fish friends, as i for one would like to give them anything that will keep them healthy :) thanks

+1 ... would love a list of fruits/veggies that we could give our babies.

Well, technically any terrestrial oils can be damaging to a fishes liver. If you're looking for a "safe" list, I'm afraid it's blank if we're only considering things that grow on land.

I noticed you had a long nosed butterfly in the tank....... do you have problems with him nipping or eating corals? I had one once it ate my Atlantic anemone one tentacle at a time!

The only thing i see him pick at is that big purple stylo but it's so big there's really no effect. Can't do clams though. I have 2 rbta that he doesn't bother at all. I feed several times a day probably more each time than most people feed in a week.

Yeah i wouldn't make it a habit but once and a while i figure can't hurt too much.

In a lot of the studies about the liver damage and terrestrial sources of oil were based on a high to complete replacement of fish oil. When using a smaller replacement ratio, these effects were not seen. It has its place in the diet, but it's not a replacement.

Well maybe there's something in it to help wrasses go terminal male!

Check out my new (sub) male bipartitus Leopard. Last night he was female. Far left in the first pic.

Still some changing to do but he's got a good start.

Thanks for the references!

(I hate to be a stickler, but links to the material would have been nicer for everyone. #1 on your list appears nowhere in google or google scholar.)

Here's what I did manage to find based on your references, with some searching:
  1. Influence of dietary lipid composition on cardiac pathology in farmed Atlantic salmon, Salmo salar L.pdf
    From: https://www.acc.umu.se/~svanberg/skrifter/
  2. Replacement of Fish Oil with Rapeseed Oil in Diets of Atlantic Salmon...
    From: http://jn.nutrition.org/content/131/5/1535
  3. Effects of essential fatty acid-deficient diets on growth, mortality, tissue histopathology and fatty acid compositions in Juvenile turbot...
    From: One of the authors' pages on researchgate.
All are interesting! I like #3 in particular!

But it's a little more complicated and specific than advertised...

It's more like they were testing the limitations of particular industrially produced (high volume; highly refined) oils. (These results should be of interest to people who are likely to eat some of these oils exclusively.)

They were not trying to compose an acceptable fruit/vegetable/land-based replacement oil in any of these cases. (They alluded to the necessities for such a thing at least in #3, but they don't elaborate.

These studies all replaced fish oil in the diet of fish with the same kind of oils we humans get warned away from now too. Rapeseed oil in particular, but none of them are good for us...they should only be consumed in very small quantities. Olive oil is one of the exceptions....a very different oil. Doesn't seem it makes a good replacement for fish either though.

And just to make it even less clear, maybe some fruits and veggies are better for your fish than others.

Check out this Wikpedia article on Omega-3 fatty acids (the main unique fat in fish oil):

In particular to our conversation, but no more interesting:

Background:

Omega-3's are a fat which fish also cannot make.

They get it through diet from....drum roll....plant sources.

Or by eating other critters that get it from plants.

It can only be obtained one of these ways. (If your tank isn't bare, fish probably get some from nibbling algae and the pods that nibble algae.)

Butter and eggs are weird exceptions.....animal "byproducts" that can be rich in Omega 3's if the mother animal is grown with access to Omega 3-rich materials like plants...and bugs that eat plants.

Strawberries and watermelon, maybe they like red because it looks like a bloody dead fish? I know that's not a pleasant thought but I can't help but wonder. Most herbivores are opportunists and will eat a dead fish without hesitation as best they can.
 
Your tank is really awesome with great coloration and pretty fish! Never would've even thought that fresh fruit would be a favorite amongst fish, but ya learn something new everyday! thanks for sharing!

My tangs and foxface really like herbs like cilantro. When I had some growing like weeds in the garden last year I'd toss some on my feeder every once in a while for them.
 
When we went snorkeling in Hawaii our hotel guide told us to bring frozen peas as it would attract many species of fish and wow did it ever! Tangs and puffers and angels went crazy for them and they were perfect bite sized pellets in the water. Worth a try if you find some organic grown produce. My biggest concern would be the potential for pesticide residue so pre-rinse and/or organic.
