As I'm pretty new to fishkeeping, I'm hoping that those of you with more experience can help me? I've come to realise that two of the fish in a tank at work are too big for their tank. I've convinced my colleagues to pass them on to someone with the tank and knowledge to suit. However, It's very hard to re-home them without knowing exactly what they are! The one in the front (Plec?)is in excess of 12" and the other one (Sailfin) is approx 8-10"
Just to add a little, the plec is only half grown, he could reach 24". I have one here who is 16" to base of tail. You may have trouble rehoming him. Try your local public aquarium. They do sometimes take them in. May be worth asking about the Syno as well.
