a good 80% of 125s look absolutely horrible in my opinion. most of them are just rainbow gravel'd or bare bottomed, are stocked full of line bred/hybrid cichlids, dying oscars, goldfish, or bichir. Bichir are acceptable fish in that case. Wild oscars are also acceptable in that case. I don't want to be gatekeeping things like goldfish, red spotted severums, EBA's, etc, but to be honest I don't like them. I've come full circle, and let's just say my username on here is outdated. Filling a $600 tank with fake decor and rainbow gravel just seems like a waste to me. 125s are a good model, and if I could afford one I'd just make a big biotope out of it. Cost for decor in that case isn't even a factor, I can easily find someone who's trimming their trees or something to get good looking branches for free, leaf litter is free, and I can sneak some nice rocks out of a lake, for free. Of course a good looking tank is very relative to your idea of beauty in a fish tank, but in my opinion, I don't understand how a bunch of big ugly fish in a 6 foot long tank with a thin layer of pink gravel and marbles on the bottom with some plastic plants, sitting somewhere in your house is aesthetic in any way. I know for 90% of a fact that it's meant to be aesthetic, because most people who dedicate a room to fish and have it more hidden away, and usually do have not so aesthetic tanks that are more made for practicality, usually won't keep fish like that in such a large tank that can be used to house more fish for one, and two, more interesting species. I do understand not having decorations in a tank like that for things like larger cichlids because they'll bang themselves up, and they do need the space for themselves. but 3 goldfish in a 125? part of the reason I think goldfish shouldn't be prizes at fairs, because they end up eating hundreds of dollars out of the pockets of the right people.
