the sick on died this morning.and i did a water change in all of the tanks including the betta one the no2 was 0 the no3 was 0 the ph went between both 6.0-6.5 each test the gh was 180 had to fix it a lot the kh still landed between 80-120 and this was before i put the water in the tank mind you and please before i hear you need to buy a bigger tank which i already know don't need to hear it again i was actually looking at tank earlier but i'm more a visual person not a reading person yes i canread words but normally i prefer to see things myself to get a better idea.but til i move in january i simply have no room for a 10 gallon to 20 gallon tank for them right now the apartment is too small they are starting to get pretty big and i've only had the two survivors for 3 to 4 months and the betta for 2 to 3 months. so until i move in a house january i' just gonna have to keep up with the daily water changes with the Goldfish and the betta though.what's the difference with the betta being fine in a 2.5 gallon and not needing to switch it i've already ready the lecture about the Goldfish

The reason the betta is fine in a 2.5 gal tank is that they don't grow to around a foot long and produce copious amounts of waste. Betta and Goldfish (despite both being fish) are very different. Goldfish just naturally produce more ammonia per unit volume of fish as a result of their digestive processes. Bettas don't. This combined with their naturally small size makes them great fish for a 2.5 gal tank.

minus the betta what fish are good for a five gallon tank once i get the 20 gallon after i move? since mom and i notice the Goldfish got pretty big quickly but what's strange the one that died he never grew at all but when i did buy him his fins were torn and ripped and he recoved from that but then got sick but not once did he ever grow unlike the two survivors who both grew wihin a week to a month.

Aside from a betta there aren't too many common and easy to keep fish for a 5 gallon tank. You could have one Dwarf Puffer fish (click the shaded name to see pictures) in there, but they are a little more difficult than you average fish. Not much else comes to mind.
