The title says it all. I have a large paludarium which I just added some Neocaridina shrimplets to last night. I checked on them this morning to find that of the ten, only one was in the front, display part of the tank. The rest had found a hole somewhere and are now in the mostly inaccessible part of the tank. The false bottom encompasses much of the tank and goes all the way across. I have a small pump powering a dripwall which is removable but it is otherwise enclosed.
They appear to be fine and are behaving like normal. Would you leave them? Try to get them to find their way back out and contain them in something else while they grow? I have no doubt they could survive back there, even thrive and breed. But I don’t really want them there. Not sure how to go about getting them out so I can removed plants and substrate and seal up any hole(s) to keep them where I want them.
Any tips on luring and trapping shrimp?
