Shrimp acting shy
So I'm new to the whole shrimp/planted aquarium. Recently I set up a 10 gallon planted for shrimp going on 3 months ago. During the cycling stage had an algae bloom so I decided to get a few otos since my shrimp have been breeding. However once i added the otos l, almost all shrimp activity has ceased. They now hide more often especially my big fire red females. This is day 3 of the otos being in the aquarium and almost all algae on the glass is gone. Water test showed all levels ok. Nitrate and nitrite at 0 and ammonia between 0-0.25 with ph at 7.5? Is this normal shrimp behavior acclimating to new tank mates or should I consider removing otos? Any information helps since I'm still new to this.
