This happens all the time when the particular Dragon begins to max out on the Release Value.

A good example is to look at Bonecrusher's Conquest. As you can see, it "hiccuped" a few times.

You are correct that the amounts are + 25% of the cost in fish to feed that dragon up to the next level, but don't rely on it. The rule of thumb would be to use the 25% as reference only, in case you miss getting the amount for one of the releases.
