They are great fish, i have an old one myself, and by old i mean i had him for 5 years! I know what you mean when you say he put up a fight, Mine has ruined nets before, making a struggle!They love the usual greens, Cucumber and what not.. They love driftwood and prefer aquariums that dont have a 'large' gravel substrate. Sand and grainy substrates are the best for them to rummage through with damaging their bristles.
I had mine in the planted tank for ages and then one night he went on arampage through the tank and destroyed everything! all the lillys has holes in and my amazon swords were torn to shreads.
they are peaceful with other fish so perfect for the community aquarium and the dont grow to the monsterous sizes the common plecs do.
overall a nice,easy,and friendly fish!
