Thanks Harry
Their getting a little large for that tank now and i'm saving for a 8'x3'x2' tank for them. Their my favourite fish and the amount of people who have them and don't look after them properly upsets me sometimes. I'd have bought loads of larger ones from lfs if i had a bigger tank but unfortunately i don't and it would be unfair on the fish if i did
The biggest i rescued from a small unheated tank and s/he was very pale and underweight and it took 2 years nursing for its colour to come back.
I always try educate people in shops where staff don't care what happens to them, I've even prevented people from buying them for smaller tanks, much to the disgust of the staff, but i don't care about the ignorant staff, i care about the fish
I don't buy juveniles since i realised they are wild and not tank bred but i would rehouse larger ones if i had room.
My apologies to the OP for drifting of topic
