I must apologse now for my lack of knowledge on keeping fish. I brought a 10 gallon tank from a local store initially for keeping coldwater fish and was talked into buying a heater and converting the same into a tropical tank......mug. Anyway, the shop stated the tank was v.easy to set add - add water - add chemicals and then add fish 48 hours later - job done. However having set the tank up I discover it needs to be cycled so decide to do this only for my mum to buy my children 3 fish - introducing 3 little platties. I have been keeping an eye on the chemicals in the tank, I have today also completed a partial water change (about 30%) as one of the platties is not well. When he went into the tank 2 weeks ago he was very skittsh, always at the top and very active - now he is v.lethargic...goes to top for a few mins then sinks to the bottom knocking into everthing on his way down, also off his food and generally not too good...also on the top of his head his scales looks like they are going black (the fish is yellow) and also the end of his body towards his tail is also going a blackish colour. The other 2 fish are very well and seem happy and have grown however (goldie) seems thin and listless......could this may be neurological or bacterial ? Whilst I may not know a lot at the moment I am commited to trying to provide the best environment for these fish !!
