My aquatic hobby was induced by my Daughter bringing home goldfish from a school trip...Wife bought a 14L tank to keep them in and I eventually ‘took over’ the duties to look after them. We added some tetra, shrimp and snails when the goldfish died off, trying to follow the advise of the LFS. Recently I added a small loach. Now my 2 snails have suddenly proliferated to 30+ baby snails. Most of the shrimp died left with 2 adults and a baby. I see the gravel has lots of small crustaceans scurrying around. The snail population keeps growing and I want the shrimp population to increase. Any suggestions how to proceed from here? I am thinking of buying more shrimp, but not sure what to do about the gravel population of small life forms.
