Do nerite snails count in the number of fish?


Do nerite snails count in the total number of fish an aquarium can support?

Welcome to the forum

Short answer - only if you want them to count

Do they contribute to the bioload? Yes, everything does. Does it mean you can't have more fish because of the snail? That depends entirely on the circumstances. It would really only be a concern in small tanks. In a larger tank, like a 29, adding a nerite or two would not impact the number of fish you could keep. In a small tank like a 5 or 10, it may. But then again, such small tanks should not be housing that many fish to begin with, so in my opinion the snail will not impact the number of fish a small tank can house because the tank size is the limiting factor for your fish stock.

Bioload is only a problem if you do not have enough surface area to sustain a colony large enough to handle it, or you are unable to keep nitrates in check performing water changes. As long as you are getting 0 ammonia, 0 nitrites and your nitrates are not escalating out of control, your bioload is fine.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta
