New Angelfish hiding after two days, not eating.

I've had a 20-gallon tank for 6 weeks, cycled with 2 zebra danios. water quality good, Temp 80 degrees, pH 6.8, ammonia, nitrate, nitrite undetectable. I change 5 gallons every Saturday, every other water change is done with reverse osmosis water from my local aquarium shop. I tend to have hard tap water, but don't measure how hard it is. Use Aquasafe with every addition of water. I finally bought two angelfish yesterday morning (both marbled, approximately 3 inches across), they were active in the aquarium shop, introduced them slowly after 30 minutes in the bags in the aquarium. They immediately went to the bottom of the tank,and huddled very close together next to the side glass until the next morning. While I was at work today, they both went into my ornamental treasure chest and now will not come out. I've tried feeding twice, once with a few flakes, not interested, watch it fall in front of them. Then this evening tried some frozen brine shrimp, not interested. I took out the treasure chest just to see if they were ok, they went and hid behind a plant until I returned the treasure chest about 45 minutes later, then both swam right back into the treasure chest and have remained there since. Any tips about what I can do to coax them into coming out and eating? Have not had this response with fish before for this long. Thanks for any advice you can offer.

Hardness may be your issue, these fish like soft water.
It might be a good idea to get a hardness test kit.

They also enjoy a well planted tank, something like Amazon Sword is good. Drift wood is good too as it will help sotfen your water.

The strange thing I find about fish is the more hiding places you give them, the more comfortable they are. Then the more comfortable they become, the more you see them. Their comfort also depends on water conditions being right!!

Moving a fish to a different aquarium usually causes some degree of shock. Angelfish are especially sensitive, and when they don't feel well they hide and will not eat. You may want to raise the aquarium temperature a degree and give the angelfish a week or so to get over the shock. Also, try to remove uneaten food.

It's possible the angelfish are hiding to avoid the zebra Danios. Zebras move fast and sometimes nip on fins; they're not the best tankmates for angelfish.

Although you were careful about moving the angelfish, the floating bag method leaves something to be desired. The drip acclimation method is much better, and you can use our SEARCH button to read more.

Finally, you are probably aware that reverse osmosis water lacks the buffering chemicals needed to stabilize pH. Quick changes in pH can shock the fish. Most aquarium fish have been raised on farms or in aquariums for many generations. As a result, they are tolerant of a fairly wide range of water parameters, including hardness. It's the changes that make them sick. To gradually reduce water hardness, you may want to add some Malaysian driftwood and/or some Indian almond (catappa) leaves.

I have two anglefish with a few guppy and i'm gains the same problem. My water is relatively neutral, Ph is about 6.7 and I use water filtered through our fridge, plus we have Missouri well water. I've made sure the temp is atour around 80
Any tips?

Try feeding no more than the fish actually eat in two or three minutes, and change about 25 percent of the water every week. Uneaten food and over crowding produce excessive ammonia which the nitrogen cycle may not be able to handle. These are common problems, so I mentioned them knowing very little about your aquarium.

You may want to test the water and verify ammonia and nitrite are zero and nitrate is below 40 ppm. If they are not,the frequency of partial water changes should be increased.

Another potential problem is the filtered water. For example, a reverse osmosis filter will remove the minerals needed to buffer pH. When that happens, pH fluctuates and stresses the fish. Well water is one solution, and a tap water conditioner like Stress Coat Plus will neutralise toxic nitrogen compounds as well as heavy metals.

I hope some of these ideas help. You are always welcome to post more questions.

I had the same issue with my marbled angel it took him almost a week to get comfy enough to start eating!He hid among my plants at the bottom of the tank brine shrimp didn't work I thought something was wrong too... I had already a small koi angel in there who was doing great! But she was a lot smaller than the marble so I went out and got another angel that was a size in between the 2.. He took to her wonderfully they did some fun synchronize swimming and the very next day the marble was coming around to the eating thing.. First slowly now it's like I can't feed him enough!! Ha he attaks the flake food I have but is still not fond of the brine shrimp. But I think yours need time to get use to the tank.. Sometimes rearranging your entire tank can disorient them enough that they forget they are shy. I had also done this in hopes he would come around to eating.. If it was rearranging my entire
Live plotted aquarium(not fun or easy to do) or the addition of the other angel... I'll never know but I know what your going thru things will work out just fine.. Angela for all their beauty LOVE hiding in your plants it's just what they do... And of they get hungry they will eat.. BEST OF LUCK!!!
