Hi everyone, I'm new here!
So we just set up a new tank a week ago, cycled it (I think? We dechlorinated the tap water and left the filter on for 4-ish days before adding fish) and then bought our lovely fish (types in my signature).
Things were going pretty swell until I noticed our platys seemed unhappy (not very active, gathered in corner of tank a lot) so I bought an aquarium heater to rectify that... I'm in Australia so I guess the shopkeeper thought it would be fine for us to not have heater, but I think he forgot we're in the middle of winter. This is the first time I've ever had fish other than regular goldfish, so I'm quite unfamiliar with all these tropical species... it's currently at 22C.
Anyway, lately we've also noticed our black moors slowing down and not being as swimmy as they were last week. Upon closer inspection today, I think they, and some of my other fish, have ich in its very early stages (by that I mean the spots are very small and some fish don't have spots at all, but are acting sad).
Unfortunately I don't have any testing kits (will buy some this weekend!) so I don't know anything about the water pH and all that jazz.
So my question is: how do I treat ich? I've read about the salt and heat treatment, but I can't find any info on whether that would be good with the various fish species that I have.
I would much, much, much rather by a medical treatment and keep up with that for a few weeks as I'm not home a lot to keep changing the water and adding salt, etc. I can do a couple of water changes, just not very often.
So any suggestions of an easy treatment that will be fine for all my fish but also effective and as least stressful as possible (I'm really attached to the little guys now!) would be great.
Thanks for your patience! Like I said above, I'm new at this
