It really gives me anxiety that both my bettas are in such small habitats. Right now, my fully grown boy is in a 1.7, and my 1 inch rescue in a gallon. Right now it is all I have been able to afford but I couldn't just leave the rescue where he was.
Today I found a 5 gallon tank at a local thrift store and it was beyond disgusting and still had all the decorations and substrate in it (seriously??!). I bought it anyway because I thought it might be worth being able to clean and house my fully grown and allow me to upgrade the rescue to the 1.7 for now.
I currently have it soaking with hot water and bleach, but I am becoming increasingly apprehensive about it hurting my fish. There is also a clear glue seal on the junctions of the glass; is this normal and safe, and would it be able to store harmful bacteria that would hurt my baby (this seems like a stupid question, but I haven't examined a lot of tanks that closely and just want to make sure)?
What do you think? Is even worth cleaning? What can I do to make sure my fish is safe?
