Hello! I’m new here but have been using this website for research purposes! I’m new to aquariums however my boyfriend is very knowledgeable and has had many In the past. He loves Christmas and I was looking for possible ways to slightly decorate our tank to surprise him. I didn’t want to just order any old type of decorations without knowing if they could be detrimental to our tank. I would be eternally grateful for any tips and tricks, insights, or pictures on how to make it just a touch festive since these are our babies now. I may just decorate the little tables on the side or something. Thank you in advance!
