Is my Pearl-scale carrying??
48x15x18 is a 56 gallon tank.
Temps for goldfish are highly debatable. What is not debatable is that they are kept in a wide range from 60 (and below for outside fish) to 80 (can get over 90 for outdoor fish). Low 70s is a good place for them to be IMO.
That being said, danios are not really tropical fish and do well in the cooler water. Too, the lower end of livebearers preferred temp range is the upper 60s. Low to mid 70s is a good temperature for a lot of the "tropical" fish we see in the hobby.
I agree about the tetras and the pleco. Hopefully the OP can confirm the measurements of their tank. And of course, water test results would be nice.
If you are unable to test the water then I would just go ahead and do a big water change. When the fish are acting weird that's the first thing you should do.
