I woke up to find a slim crack across the front of my 37 gallon tank this morning, so now I am in urgent need of a new tank. I will temporarily set up a spare 29 gallon tank today until a new one arrives, apparently I'll have to order online. The tank houses 3 young fancy goldfish. I had planned on upgrading soon, but have no time to do a lot of research now. I am looking at the SeaClear 40 gallon acrylic tanks online, does anyone have one? Is there room for two Aqua clear 70 HOB filters? I can find no descriptions anywhere of how much room there is on the top for filters. Thank you.
