Hey,
Some of my fish sometimes have little spurts where they swim sideways across my sand/stones, originally i just thought it was my ruby shark as my other fish didn't do it but yesterday i picked up 2 baby clown loaches and a puffer fish, and i noticed the loaches did it a bit, should i be worried?
I looked in the FAQs and it said something about parasites in the gills but i can't see any redness on the ruby shark
Also, i have some snails with the cone shell in my sand, do they do anything bad for the tank?
Should i try and take them all out?
Also, i got my puffer yesterday and is it normal for them to hide and bury themselfs in plants? (She only did it since i put more substrate in, but was very exlporing when originally put in)
