I think it depends on the
specific vitamins that are in the cichlid pellets. Do you know what they are in detail?
There is a consensus that Rangen brand pellets are a good staple diet for axolotls. They also have fish as a main ingredient, but because a main diet of fish can cause thiamine deficiency in axolotls, the Rangen pellets are fortified with Thiamine as well as other supplements to make them nutritiously balanced for axolotls.
Here are the ingredients in the Rangen pellets:
Fish Meal, Wheat Feed Flour, Blood Meal, Fish Oil, Ascorbic Acid, Biotin,
Choline Chloride, Folic Acid, Niacin, Pantothenic Acid (d-calcium
panothenate), Pyridoxine (hydrochloride), Riboflavin, Thiamine
(mononitrate), Vitamin B12 supplement, Vitamin A (acetate), Vitamin D
(d-activated animal sterol), Vitamin E (dl-alpha tocopheryl acetate),
Vitamin K3 (menadione sodium bisulfite complex), Copper Sulfate,
Manganese Sulfate, Potassium Iodate, Salt, Zinc, Sulfate, Ethoxyquin
(preservative), Proprionic Acid, Sorbic Acid, Propylene Glycol,
Canthaxanthin.

I think if you don't already have these cichlid pellets, then buying Rangen Pellets (like at Edsflymeat.com) is a terrific choice as a staple diet for your axolotls. They are pretty cheap too, and last long.
All the best.
