I have 8 tinfoil barbs.
One of them is is well over 1 year old and the other 7 are less than 10 months old and all of them have lived together in my 280g tank since last November and are all growing well and appear very healthy.
Obviously, the older barb was MUCH bigger than his 7 buddies when they were first put into this tank, but now the younger 7 barbs have caught up the older older barb in size and have grown bigger than the older guy.
The older barb has a slightly different colored dorsal fin and tail fin than the other 7.
Are these fish different breeds with different growth rates??!!??
I have attached 2 photos.
The first photo is of the older barb with a full black dorsal fin and full red tail fin.
The second photo shows the same barb on the left and 2 other barbs. The other 2 barbs have a black and red dorsal fin and black and red tail fins
