The heart shaped one is apparently 2g. Didn't check the others but judging by dimensions the heart seems to be the most spacious. What do you think? Plausible good idea? Tbh my only fear is finding something that can handle that much weight. Because if it falls... *shudders*
I'm renting, like a lot of you here, so my go-to is one of those adhesive wall hanger. Literally the heaviest thing I ever hung on those is a key. If you don't have my problem however, what do you say? I'm not looking for a new tank atm just wondering
Quick note about the seller: despite the horrific images they did state that no fish other than Betta can live in such a space.
