How slow/fast development should be

[layna]

Hello, ive been reading this website for ages but became a member today after searching A LOT of posts i think im doing okay, however a few questions.

1) my lotls are around 4-6 weeks old now and i can see one has legs and is starting to get little fingers, but the other barely has stumps. is this normal?

2) the smaller one with stumps has gills but they seem very small and not as full at the others? is this normal?

any help would be great thanks

Both of those are normal. Like people, axies grow at slightly different rates. Also some axies have smaller or larger gills than others. Sounds like they're doing great

thanks, im just a bit worried becuase i started with three (admittedly one was very white) and the white one died, there only just getting their little front legs so there not very old and i feel like a bad mother haha.

they have a tendency to have their tails floating a bit and they have only just started doing this so im putting it down to them not being used to having legs, so their a bit off balenced maybe? or so i hope!

ive just bought a sponge filter to try and keep their tank a bit cleaner but im not sure on weather to use it or not, any help would be brilliant
