Well first off, fish dont get better in a couple of days... second you already know that you have way to many fish in that tank. IMO you need to figure out which tanks your gonna keep running and then put the appropriate amount of fish in those tanks!!! Like the umbee should be in the 75g by himself for now and use the 180 for a small community untill your able to downsize on your fish. Truth be told.. your eyes are bigger than your stomach bro. and i hate to have to say this now because over the last few months everyone has tried to tell you. You cant have all the fish that you want with only a couple tanks!! Time to man up and be responsible for the fish your keeping.
There are alot more fish i really want but i dont have the proper space to house everything long term. Hell, i could get all that i wanted and cram everything in the tanks that i have but i would shortly be running into major problems ie; high ammonia levels, aggression issues, nowhere to seperate fish cause im overstocked. I mean look at me, I am having to downsize myself to be able to properly house my festae project. and to throw a spin on it, my electric has jumped to 500$ a month and my wife is really breathing down my neck to cut costs. so im pulling strings, selling stock, re-did filtration to be more cost affective. It sucks but if im patient ill be back where i want to be by summer
To sum this up, i say put the umbee back into the 30g by himself and leave the temp around 80. keep the water very clean and add a lil salt. I hope he comes around for you because it would be a shame to loose a umbee with that kind of potential.
