I've had my 2 Black Moors for a little over a year now. The one black moor is acting fine still swimming around the tank and acting like he always does. The only thing different about him is he is turning orange but i heard that that can happen due to warm temperature water. My other black moor for a couple months now has been laying on the bottom of the tank. At first it was just a little bit every once in a while and if i would come up to the tank they would both come see me. Now he just sits there even if i put my finger to the glass. He eats the food that floats toward him every once in a while. But i'm getting worried cause he doesn't swim around like himself anymore or come and greet me. He is still almost all black other then a couple of spots on him are orange. What should i do?
My tank is a 20 gallon and I give them the vegies they can have and they get dried shrimp. I have a heater that sets the water to 78 degrees. I have a bubble airrater. I try to do a third water change once a week. I use stress coat and the stuff that makes tap water safe for fish. I'm gonna be doing a 50% water change tomorrow. Cause the tank is pretty dirty right now. I was afraid he had a gull bladder problem half way through the year i got him but the rest of the year till now he still likes to swim fast to the top gulp air and blow bubbles but its not often, just an every once in a while thing. I have really crappy paper strip water testers that i heard don't work very well. I'm hoping to get something better. In September I had to treat them for ick. They were covered in head to tail fine in it and almost looked white. But it completely cleared up and haven't seen a spot since and they acted fine after the treatment. I just don't know what else could be wrong.
First thing is your tank is a little too small for moors, they do need room for that. Second is the temp, You should lower the heater and leave the temp at 20, however do this slowly or it'll kill the fish.
And you mentioned that they've had ich? It's actually a sickness only occur when water quality is bad (high in ammonia,nitrite and nitrate). You have not mentioned what type of filter you are using so I assume that you don't have one? Filter is very very important, especially for those fish. The only reason why moors and other gold fish can survive so long without filter is they're hardy but time will kill them.
Even your test is crappy, try to use them and see if there's ammonia trace. Reduce feeding and do a big water change as soon as possible. Remember to match the water temp before changing.
Keep in mind that test kit and proper filter is very important too, you'll have to act fast or they will die :)
