Are Freshwater aquariums just as Biodiverse as Saltwater counterpart?

bluesky2111

I've had this question for a long time. As a hobbyist on both sides, I thought saltwater has more biodiversity. But recently I found out that freshwater isn't far behind, though I could be very wrong.

So in SW other than fish and corals, there are a bunch of critter, ranging from microscopic level to visible. You can have a wide range of inverts such as Snails (conchs, trochus, cerith, astraea, stomatella, cowrie...), urchins, feather dusters, sea sponges, shrimps (pistol, skunk, fire red, sexy, peppermint...), crabs (emerald, hermit, halloween, pitho...), pods (copepods, amphipods...), worms, sea slugs, and a bunch of other things that pop up out of nowhere.

I read that in freshwater (aquaria) there are many other little stuff, though could be not as visible as in reef. You can have planaria, hydras, black/white worms, snails, crabs, frogs, even pods,...... The thing is, I've never had all of these in my tank and I did try to look for them. I do have some worms, but they are very very small. My oldest tank is 3 years old and heavily planted.

So in your experience, is freshwater aquarium environment biodiverse? What about in the wild like lakes and rivers?

Get in the wild its a whole different ballgame. A lot of insects are attracted to the water, plus all the small stuff you may be able to see with the naked eye or not. Amphibians, reptiles, inverterbrates, fish, plant life, etc.

The more fun part in the wild to me is watching all the land life interact with the water life.

I don't know about saltwater, but I would like to also. in one of my fresh tanks. it had no fish, and little flow. and after about 2 weeks, there were thousands of cyclops, worms, daphnia. it was kind of terrifying, but it was also one of my favorite tanks because it was so educational.

Yeah I’ve always been kind of a saltwater dreamer because corals are so cool! And all of the saltwater invertebrates are great. I didn’t know about all the little worms and pods. I’ve thought about how little bugs like that that could reproduce in my fish tank and feed my fish would be awesome. I’ll have to look into the things that were mentioned here.
