hi guys lately i notice my fish acting weird , not so sure if this is normal.
i'm a noob in this so if its normal , please let me know

1. neon tetra - i have a shoal of 14 (intend to add 6 more ) , but somehow i always find a pair of neon tetra seperating from the others , and they sort of , stay still together at another part of the tank.

2. siamese algae eater -i have 4 of them found them always together , like a school of fish like that.

3. OTO - i only have 2 for now , 1 seem to have a larger belly and the second one is always swimming after it

4. corydoras catfish - 6 of them , love digging my APP , will they uproot my lawn of APP ?

5. malayan shrimp - have abt ... 15 i guess (minus all those i pick out dead) found a very small shrimp and some BROWN one !!
any comments

2. dun worry
3. dun worry
4. maybe, but mine don't
5. when they pack shrimp, they don't sort 1 by 1
you might have gotten some other species
it's normal

1. Don't panic, just observe the 2 for disease.
4. If the growth is compact, quite a high chance of some being dislodge. You might get some "jungle trials" criss crossing the patch, especially along the glass.
