I bought 2 wood shrimp yesterday and put then in with my zebra plecos and since then I noticed the zebras are much more active, even right now while it is still daytime. I also have 3 applesnails (plus tons of babies) in this tank. They keep laying eggs (I have 7 clusters right now, more then even my puffers can eat) so I would like to move at least one of them out (once I figured out what's boys and girls. Whenever I see them mating I will move one of them out until there is no more action going on. That's why I thought the filter shrimp would be a good addition. Now I'm not so sure anymore.
The zebras never minded the snails. But could they be after the filter shrimp? I have not seen one actually going after them but they sure are moving around a lot more. Anyone kept those together before?
I had 2 filter shrimp with L174s (Peruvian panters, same size and food preference as zebras) and a bristlenose for several months. Then one died a few months back. I bought another one but that one was so weak the store clerk told me they would replace him with a new one if he should die. He lasted 3 days. Then the other one died or got murdered within days of it. I only found small pieces of shell, the rest was eaten. I had that last one that died for 1 1/2 years.
Could the 174s have gotten big enough to take on a filter shrimp 2 1/2 inches long? And may my zebras that are about the same size as the L174's (around 2 1/4") be a threat to them as well?
The only other place I could put those shrimp are with Aquamax, my goldfish with swim bladder disease. He could not catch them even if he tried but that tank is really too small for 2 filter shrimp.
