My 2 orange spotted blue file fish came from another hobbyist when they were so small that he had to get rid of them because his tank's occupants were too aggressive eaters. The little girls were paper thin with just protruding gill cover bones (cheekbones!) Over the time I've had them, they have doubled in length and quadrupled in thickness. They have also added spots to their lower fin, so now they are both males...
I have a magnificent foxface that arrived with PTSD. It wouldn't come out to eat with me in the room. This PTSD behavior took months to overcome, but eventually the foxface trailed my copperband butterfly fish around, seemed to be fine only if it could be within a dorsal fin of the CBB. We could tell the CBB was often annoyed by the foxface shadow, but a CBB's not very effective in fighting for its own personal space. Fast forward a couple years, and this foxface beauty swims alone, without worries and even greets me most mealtimes (lunch & dinner).
My most recent addition was a Red Sea Regal Angel and this beauty hid for 2-3 months in a cave, even during feedings. The sponges it was eating inside that center cave are now mostly gone, and this fish also has gotten comfortable coming out and swimming freely. This fish LOVES zoas... so I'm getting used to the bare spots where it has eaten all the zoas. We've named our Regal 'Mr Bitey' because so many zoas are gone. It eats them in rows, sort of like we'd eat corn on the cob. The fish is way more colorful than any zoa, and I knew going into this that potentially some coral eating problems - but fish over corals for me!
Weirdly, with the recent addition of this angelfish, my copperband butterfly fish has expanded its food selections from only mysis to much of the LRS Frenzy lines. I have been feeding that for years without the CBB paying it any attention, but as soon as the angelfish started leaving the cave to eat, the CBB also wanted to eat a more varied diet. My CBB began grabbing pieces of LRS that I feel are too big for it, yet its beak must have become stronger because it can tear apart food bits into parts that it can eat (those larger bits are intended for foxface). I'm a little worried my CBB is going to choke on the larger foods with this new behavior, despite there are still plenty of mysis in every meal portion.
