What fish food is safe for my sensitive stomach cat on Royal Canin?
I don't think Royal Canin makes a dedicated fish diet for cats. i'm not sure why you are looking specifically for a fish based diet, if it is because you know for sure that he is doing better on such a diet i would recommend ORIJEN Six Fish Cat Food.

Why are my fish dying with grey spots? How do I treat their illness?
Check the water chemistry. The discoloration could be due to elevated ammonia levels which can cause "burns". Use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. The Neons (blue fish) appear to be infected with Ich, a parasite. Treatment is possible with commercial products found in the local Petco. Follow label directions carefully. You will need to treat the entire tank until all traces are gone. Removing a lump from your fish on your own is never recommended. You can cause severe injury. Most broad spectrum antibiotics (Kanaplex, Maracyn, Maracyn 2, etc.) found in the aquarium section of the local Petco should help treat or prevent infection. Choose one and follow label directions. Remove the carbon filter insert during treatment if indicated. Maintain pristine water quality via filtration and regular partial water changes to aid in recovery. You can feed frozen worms, just thaw then first in a small cup then place them in the tank.

Why is my fish upside down and bloated? Is it swim bladder disease?
This is a classic sign of swim bladder disorder. Check water quality and chemistry. use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for 0 ppm ammonia and nitrites with nitrates at 20 ppm or less. pH should hover around 7 and water temp should range between 65 F and 72F. Perform a partial water change is necessary to stabilize chemistry and improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Pristine water quality is the foundation for recovery and healing. Next, fast her for 3 days. Resume feeding bits of cooked, shelled green peas until she is swimming and defecating normally. You can fast her one day a week in the future and offer green peas to maintain regularity. If symptoms persist, consider a broad spectrum dewormer and a broad spectrum antibiotic. You can find both in the aquarium section at Petco. Follow label directions carefully and remove the carbon filter insert during treatment in indicated.

Is my 5.5-gallon tank filter too strong for a new baby betta fish?
If you can adjust the filter flow, it should be fine if you turn it down. If not, you may need to use something to redirect the outflow to decrease current strength. You can use a piece of sponge or pre-filter in the intake to prevent a small fish from being drawn into the filter. Although live food is nice, it can be difficult or time consuming. Live food can be purchased online and typically includes instructions on care and feeding. Food companies all offer "micro-pellets" for smaller fish which is also an option.

My Pacman frog ate goldfish. Are feeder fish safe for frogs?
Feeder fish can be added to the diet, however you must consider the source. Typically these fish are kept in a tank with hundreds of other fish. This predisposes them to infection and parasites which could be transmitted to your frog. As an occasional treat, they are fine. Stick with responsibly raised insects and nightcrawlers. Another treat to be given occasionally would be a pinkie (baby mouse).
