Alex's Mobs is not great, it has a lot of one note mobs with "uses" that don't really add much besides some flavor, and no ambient mobs. The mod strives to have only useful mobs but will shoehorn uses into mobs that wouldn't really need them solely to justify their existence when they're already justified. Many mobs are just vanilla thing but "better", such as almost every tame being a better wolf, the hummingbird being a better bee for crop pollination, and the Laviathan being a better strider. Most mobs don't have interesting interactions with one another or the world, so a lot fail to add much life to the game either, outside of existing at least. The art isn't very vanilla-fitting, most mobs in the mod lack the goofy stylization that vanilla mobs have, rather having more basic "accurate" proportions. There's some gems, like the catfish, but unless you need filler for a modpack, especially a zoo modpack, where the collection aspect is more important than the immersion and usefulness, I wouldn't suggest Alex's Mobs. Use a mod like Spawn instead for more interesting animals use/design-wise, or Species for more interesting fantasy creatures.
