Help: Beginner Filterless tank shrimps gathering at the top
Hello! I have an issue as per the title. Last time I posted I got a ton of help. We let the tank sit for a month and everything went well. Water parameters are normal. We have had the shrimps now for around a month and we think we can see eggs at one of them. However since a couple days they have been gathering at the top. Not all but it’s not their normal behaviour.
Is there anything I can/should do? Like I mentioned in the title the tank is filterless so I don’t know how to add oxygen.
Thank you for your help!
