Algae and Olive Nerites

[steve18]

Will my nerites get big enough for my 75g tank?

i have green algae issues in my brackish tanks. I bought 10 pea-size olive nerite snails (i think from mgamer), and put them in my 10g. they work amazingly well. but when i tried to move them up to my 75g with my large fish, if the snails are on gravel, they all simply get bowled over (and stuck upside down like helpless turtles) from the turbulence of fish swimming by, so i moved them back to the 10g. now i rotate the algae covered decorations from the 75g to the 10g, let the snails scour them (it's amazing how thorough they are), and put them back. my nerites have doubled in size from very small pea to large pea, but unless they get really big, i think this is the best i can do. any ideas?

The size range does not hover more than 2". 1.5" would be the max for the ones you have. You'll be fine keeping all ten in a 75g. The only problem is getting adequate algae supply for them unless you have rampant algal growth. Nerites are horribly picky with their foods preferring algae in general. You could try pea flavored gel food and cross fingers they'll try vegetables (which fortunately others are lucky their nerites ate). Mine ate cucumber slices aside from the algae.
