Hey, Thanks so much for the tips. Will go researching for a good cannister filter (but I think I will retain it with original ugf and see what happens).
He will get as big as 15cm and very fast growers,also he tends to bother other fish.
Wow, mine are just over 3 cm right now. I just noticed before reading this forum that they were indeed growing but I just presumed they'd grow as big as the cory's (5 cm right now).
