Hello everyone, I came to the hard decision of selling my tank, I have just started a new business so I barely have time to keep up with the tank and I wanted to downgrade to a smaller tank I have so it’s easier for me to do water changes and such, I have a blue hippo tang and she’s acting weird, hasn’t been eating and now is losing and regaining color while laying on the sand, but here is my question, I have a 75 gallon tank with a 25 gallon sump and I wanted to transfer my mandarin and my 2 clownfish to a smaller tank which is 13 gallons, how could I make it a safe transfer for the fish and how could I reuse most of the stuff I have in this tank to make the process of recycling the new tank quicker… thank you everyone!
