I would like the members opinion on what to do about this siamese algae eater. It was raised in my tank from a small size. Now it is quite large and delights in torturing the 4 pearl gouramis in my tank. This happens particularly at feeding time.
This aggressive behavior won't improve over time and might even worsen. It may be time to part with the Siamese algae eater. If you wish to do so, you may enter the fish in the club's mini-auction. If you join the club's membership ($20), you will receive a 70/30 split of proceeds from the sale. Non-club members receive a 50/50 split of proceeds from their items.

I own a community tank with several catfish and a few rainbows, but I never thought my collection of rare catfish would actually spawn for me. I have 6 Tatia Intermedia, 3 Tatia Musaica, and two Otorongo wood catfish(also Tatias).
Last Monday, October 14th, I was doing a water change as per usual, when I started trying to shake out debris from inside my thick and bushy bolbitus plant. In the process I discovered a Tatia Intermedia nesting with about 200 of her eggs in the center of the plant. I of course decided to remove the eggs before any snails or catfish ate them.
I now have a small container with all the eggs in it that I do 25% water changes daily. I use the tank water from the tank I have the parents in to avoid any tap water related issues.
This past Saturday, October 20th, I…
I think it’s safe to assume the Tatias are going to steadily keep breeding, this is the third and the biggest clutch since they started in October
