No because until I heard Neon's external filter on a big tank recently I had the idea they would be noisy like an airpump or a hang on the back variety. I haven't ever seen a small external one in action, but is something to look into one day. I will store your suggestion in my memory bank as I'd rather have a plant there.
Squirt, tank is about 51cm long by 28cm high and 30cm deep - from memory and not measuring it. It was the longest we could fit on a particular piece of wall so had it made. The filter is Eheim Pickup 2006, lighting is now an over 1 year old 14000K sensen that I scored at a petshop closing down, 8 watts I think and the lights are on about 6 hours a day only. No Co2, it's a low tech tank. It's so low tech I'm freaking out a bit about this quite rapid growing new plant. I'm hoping it uses up whatever fertiliser it can find and then slows down like the other plants :sml2:
thanks for the compliments
