Who Gives A Fish Forums

I've seen people use Lego bricks for decor. As long as they're clean and don't have small parts, they're safe. My kid's old Legos are now part of our betta's tank, and he loves swimming around 'em.

I've been thinking about your tank setup and I reckon the problem lies with mixing victorkento4s and malawi's together, they just don't get on. You've got Sp. 44 and other dominant species in there, that's a recipe for disaster, they're bound to clash. And I see you've got multiple Alunocara species ...

Keep 'em thriving and enjoy the progress
