My elder mom has a black moor single female. The fish seems to lay eggs, scattered around her tank every week or two. This forces my mom to clean the tank as often because it gets cloudy and starts to smell. Is there any way to deter a moor from laying eggs as it’s not an easy task for my mom to constantly be emptying and cleaning the tank. Any insight would be greatly appreciated! There is a male beta in a nearby tank but this has been going on before she got the beta as well.
