please & thank you
Sorry for your friend's loss... but without details as to what happened leading up to the death, nobody can really offer you much help here.
What size container was the fish in?
What was the water temp?
How often did she feed the fish? How much and what foods each time?
How often did she change water and how much each time?
Did the fish lose color, appetite, develop fuzz on fins or body? Any symptoms you can describe would help a lot... did he lay near the bottom, did his eyes swell... anything you can offer here would be of big help.
The other things to consider are whether the fish was sick when she got it... and how old it was... how long did she have it? Most bettas found in the stores are already at least 1 yr old. The average life span of a betta is 3 - 4 yrs and genetics also has a lot to do with it. Over the years the betta has become so popular and has been inbred, cross bred, etc to produce specific fin styles and other traits.
If you and your friend can answer the above questions I may be able to give you some insight as to cause of death.
Tell your friend that the safest thing to do now is to sterilize all of the tank and decorations, equipment... Once I know the situation I can coach her on how to do this in the safest and least expensive way possible.
