wednesday13 yeah, mine already slow down his growth. Now it takes more than a few days to get 1" of growth. If the fish being kept in a natural pond, i suspect they could live more than 25 years & perhaps grows even bigger
I was picking up some live food at my lfs, and they had 2 x 3" Well for sale. They are wild type, one much darker than the other, and were priced at $29.99. This is the first time I've ever seen for sale, so I bought one (of course). I am surprised that they are even legal in California, but I checked the Fish and Game list and they are not on it. Talk about an introduced species from hell... I'll post some picks when it settles into its new tank.
He’s difficult to photograph; he’s been lurking under a bunch of water sprite and bolts when I try to put light on him to photograph.
What I’m wondering is what to do with him once he’s too big for the 150g I’m gonna put him in?..
It sucks they sell these fish, not to mention arapimas, etc at the lfs, not to mention they could easily naturalize, if not already.
Wels species you can tell by their number of barbels. European wels have 6, other species have 4. To keep it simple, as long as there're buyers, they will keep coming.
All catfish go through spurts of growth and periods where they don't.... studies were done in France that concluded wild Silurus Glanis reached an average of only 36" over 5 yrs and they only consumed 1-1.5lbs of food per week. No evidence was found against them harming native populations in their non native waters either. My own work yielded at 52" Silurus Glanis after almost 7 yrs. Id estimate around 35-40lbs. These fish are in no way monsters or man eaters. they are very personable and make great companions... pics shown by fishermen of the 6'+ are 25yr old or more fish... anyone keeping one at home will most likely never see that. 2 many things happen out of our control with power/equipment failures.

+1Lol, that's a Wallagonia leerii. It is indeed in Siluridae family but not in silurus genus. The forked tail give it away. Apart from Ompok sp, Wallagonia sp have longer mouth. Seeing it that small & plentiful, probably farm bred in Thailand. They're available year round.
