So I've had my angel in my 55 for about a week now and I was wondering about how old do you think he is based on his size. I was also wondering if anyone knew about how many more inches in length and height he would grow. He doesnt have those long flowing fins as some type of angels have so is 6 inches still obtainable? Heres the pic!
hard to tel how old just by size...it could be stunted..roughly.......quarter size body without fins would be about 3 months old if decently kept...and if properly kept in a 55 where there are at least 30% water changes done twice a week or so it could reach 8" in height from fin tip to fin tip..
Pterophyllum Altum is the largest of the angels reaching as much as 20" tall.....unfortunately they are not exactly easy to get ; are fairly pricey ; and are much harder to maintain that the other angels....no one is currently breeding altums on a commercial level and only a couple of people are breeding them even on a small scale...
between 4 and 5 months i would guess...feed it good....keep it warm.(80-84)...and do lots of water changes...it will grow to become one of the most graceful and stately fish you will ever see...
