african lungfish lost color

I have an african lungfish not sure what species but all of a sudden he got sick and his eyes glazed over, just his eyes nothing else on his body ofther than some natural slime. I got him over that and now(about 2 weeks later)he has lost his color. He turn extremly pale in less than 24 hours but still has an appetite. Need some advice i dont want to let him go.

how big is your tank?

40 gal tank, he is about 18 in long. The tank is 36 long x 18wide x 17 H

lungfish arent bred for color. they are generally inactive slobs in aquariums. lol.

u might want to go for an axolotl instead. same general body type. cuter, relatively active and smaller sized. ^_^
essentially these are just like water dogs

Well mine has always had a nice deep color, very active hunter. Would not classify as a "slob" cleans his tanks of all meals. Thats why i need help as to why he would loose his color in less than 24 hours

hmmm you should post a picture to ID it. because if you dont know the species 40 gal might be getting too small. most lungfish spp can grow to 3 to 6 feet, fish dont grow to the size of the tank.

Yes but he is only 18in long in a 36x18x17 tank 40 gal tank would that cause the rapid color change?

It is not allowing me to post picture

Well Mchumba is doing amazing now

heres how to post pics.

do note that as your lung gets older and bigger, itll need a bigger tank because itll get larger than 3ft easily. also i will get less active.

as a youngster it mightve been sleek and active, but as an adult; fat and sluggish. like the average american

Thanks but i am smarter than the average bear, I bought him at 17in knowing all the odds and ends.

well thats good ^_^

sorry i could help much with my limited knowledge. you should check out forum sites that cater to monster fish keeping like ......

also do not think your lungfish is dead, even if it looks dead. lungfish have learned to endure some harsh conditions by secreting a mucous substance around them--like a snot cocoon that looks like key lime yogurt. it looks very dead, but in fact hibernating. i guess the only 100% sure way of telling whether a lungfish is truly dead or just in hypersleep is it starts to rot.
