Hi Heather, appoligies for not replying sooner! When i do a water change i refill from my pond in the garden, roughly half a tanks worth and ive purchased a battery powered gravel filter to suck up any leaves and debris from the floor of the tank.
Things have progressed extremely well since my last post and the fry have grown well-there are now around 20 little stickles just over a centimetre long, all the larger fish have been removed back to the pond exept for the Millers Thumbs and i now also have some new additions which came with some fresh weed i put in the tank, these are some big tadpoles without signs of legs forming(im presuming they are toads which i will release in the garden when the time comes) there are also some aquatic 'mini beasts' in the form of 2 different types of Dragonfly Nymphs, One is elongated and looks like The Predator(which is infact what they are i no)and the other one is short and dumpy but both are feeding on watershrimps and the occasional small worm i drop in.
Once the pump filter has done its magic and cleared the water enough i shall endeavour to post some photo's but im not guaranteeing anything as they dont come out of hiding much, but when they do il try get some pics.

Jack.
