How can I tell if a decoration is betta safe before adding it to the tank?
Start by checking that every surface feels smooth to the touch and that any holes or tunnels are large so a betta cannot snag fins or get stuck. Choose pieces with stable bases or secure attachment points so they will not shift or tip as your fish explores. Prioritize designs that provide cover without tight gaps so your fish can swim freely.
When should I replace or remove a betta tank decoration?
Swap out decor when it shows wear that could affect safety, like cracks, rough spots, or a wobble that makes it unstable. It also makes sense to remove a piece if it starts to crowd the layout, blocking open swim space or easy access to the surface. Keeping only durable, well-fitting items helps reduce stress and maintains a clean, engaging environment.
