Yup not much you can do about that.
I would get Red Tail tinfoil Barbs cause they look great and are pretty hardy
a fancy goldie, but then it would have to ditch any cichlids, and just go with tetras and a goldie, nice, colorfull, and peacefull, maybe even some mollies, or platys, and early is a good time to teach kids to not hit the glass.
TIN FOIL BARBS? they get HUMONGOUS, they make 90 gallon tanks look tiny!
haha
