Hello forum

pretty new here so be kind...

basically I want to know whether fish tanks which have many angles are safe for my fish. I have this fish tank that I received as a present last month but still haven't used http://fishtankbank.com/corner/

And obviously it has corners and a few angles which could be sharp. Is this type of fish tank safe?

thanks

Also this one too http://fishtankbank.com/octagon/

thanks!
