I have been looking around the site for a while now trying to properly diagnose my lil fisheys problem but I can't seem to figure it out.
I am a new owner of a small male blue/red betta fish whom I adopted from my housemate as he was fighting with the other fish in her tank.
Over the past few days I have noticed some small blacks specks/spots on his pectoral fins close to his gills. Ever since I got him I have been in two minds whether he is well or not. He seems happy, he is active and very social [he swims up to me whenever i come over to tank.] I am feeding him about three pelets every day, which may be too little, and every time he chews it up and spits it out and grabs it again! I think this is because they are too big for him so I'm gonna change him to other food.
I now have him in a [roughly] 3 gallon bowl. I clean the tank and do full water change every 3-5 days. I do not have a filter nor heater, but I plan on getting them both. The biggest thing that concerns me is the temperature of the water, its cool to touch, but not cold, as the room is always warm.
Here are some answers to from a betta fish question form, it might help:
The pH is nuetral, i use normal tap water with special liquid called 'stress coat +' to safen the water and to remove any cholorine. There are two fake plants in the tank and some stones. The tank is in indirect sunlight during the day sometimes. There is no artificial light in the tank. One of his gills seems to stick out more than the other, almost as if he uses one more than the other, and also the edges look a bit 'rough'.
Oh! another bit of info is that sometimes when he is up at the surface he blows one decent sized bubble. I have read that this means he is happy but could also mean he is sick. Sometimes when he is at the bottom of the tank he accidentally sees his reflection and 'flares up'. This only happens every now and again though.
Any help would be greatly appreciated, I'm worried that I'm not looking after him properly!
