I've been very concerned these past 5 days. Here is some Info 1st off: I have a male Betta fish, Rocky who is 1 and 1/2 years of age. He lives in a 10 Gallon tank, with various natural plants, a nice large piece of Wood, substrate is ‘Eco complete’ and my filter is the “zoomed nano 510”. Rocky shares this tank with an Otto and two Amano shrimp. Water temperature stays between 76 and 78. The Ammonia levels are 0. There are no nitrates found. PH is usually at about 7.4 on average.
He's always been a hungry little guy that used to enjoy Betta Pellets, Freeze-dried Bloodworms, Freeze-dried Bribe Shrimp and various other Betta Foods, as well as pees. I feed him once in the morning Weekdays at 7:00AM, Weekends at 10:30AM and once night between 10:00PM and 11:00PM. I try to vary his foods frequently.
Here is my Concern: Since 5 days now Rocky refuses to eat even when directed to the food with my finger or even when directly held in front of him. He swims away from it. He also mainly spends his time at the bottom of the tank now.
He does not display any physical signs of illnesses or disease. No clamped fins, his color, a pale pink, is glowing, no injuries or any cottony growths. There is no bulging of caving of the belly. His belly is a good, normal size. Nothing has changed in his environment recently. He has a great air supply in the water to do a spray bar, one of the best filters. Frequent water changes.
Rocky simply stopped eating 5 days ago for no apparent reason. Sometimes I see him opening his mouth very widely, and then he simply swims to another location and sinks back to the bottom. He has done this once before, but only for 3 days. As this behavior came on it went away.. But not this time.
Another sign that I thought to be a good sign is that he still will occasionally flare at the Otto. He still seems interested in things, but he's just not moving much and not eating.
I’ve tried various things to see if it would help: I did a large water change (even though water perimeters were very good), tried to feed him various different foods each day, re-arranged to piece of wood as to create more caves to explore, in case of boredom.. but nothing helped.
I've tried researching this issue without avail. Any help with this issue would be greatly appreciated, as Rocky is part of the family and we are so worried about him.
Thanks in advance to anyone that could help. I'm worried sick :/
