I have not bought any snails so i assume that they were eggs on the plants they are little brown snailsabout 1mm across and my tank plants are suffering- today i plucked out a 'branch' off a plant and my tank now looks nothing like the previous photos where its perfect what should i do? I was going to get some clown loach anyway so maybe i should get them? I don't know- I want something natural so I can get fish asap.
