ATF Set up! - feedback

  • We are currently upgrading MFK. thanks! -neo
Looks like FATF to me. The one in the second pic unquestionably is.

Here is my old, 100% confirmed FATF for comparison:

You have a beautiful aquarium and fish!

Chicxulub, I've been an admirer of African Tiger Fish for years and would like to locate some later this year. I've recently read the introduction to ATF that I believe you wrote and is a sticky on this forum. After ready the sticky, I'm a little confused at some of your comments on this thread. You mention that OP's fish should be much larger by now and that his aquarium (with a footprint of 8 x 2.5) is definitely nothing more than a grow out tank and then you identify them as Forskalii. Based on information in the sticky, it would seem as if this aquarium is more than adequate for the fish and that they are appropriately sized for FATF. Have I misread something? Honestly the species abbreviations have been confusing me a bit. Seems much easier to to just use the actual name of the fish.

Thanks
Rex

Rex,

The sizes that I listed in the sticky are for a single fish being kept in a specimen only tank. In a group or with other species, a (sometimes much) larger tank is required.

As for the abbreviations, the actual scientific name is what it is based off of. There are five species, vittatus, tanzaniae, brevis, forskahlii and goliath. Each of these species begins with a unique letter. The first letter of the species of the fish- V, T, B, F or G is used as a prefix for ATF, which is shirt for African tiger fish.

Essentially, FATF means forskahlii African tiger fish; it is used because it is much easier than typing Hydrocynus forskahlii over and over.

For one it would be OK but he has seven lol

That's a nice setup and some nice looking fatf, avoid beefheart and such stick to whole fish and a good pellet. Beefheart makes em big fast but too much fat. I wouldn't be surprised if it did have to do with desalinated water, have you ever tried to test for salinity or even TDS

Thanks for clearing things up a little. In the OP's situation, how many FATF would be suitable, for life, in his aquarium?

Thanks
Rex
 
Bigger is always better for these guys. When dealing with a fish that can hit a sustained 35 mph, they need all of the room they can get. Please re-read the blurb in the sticky for specifics on this. Again, the sizes listed there are for one fish in a bare tank with loads of current.

There has been an interesting development in my system.

Bearing in mind that these fish have been kept together for the last two years in a much smaller system with no decor or substrate etc, with only two sponge filters.

Since moving them to this larger planted system, the fish are showing a lot of aggression towards each other, with the largest being the most aggressive.
I have moved the larger one until I can understand why after all this time, it is only until now he has become aggressive.

the rest are much more similar sized, however there is a small amount of aggression.

Can you help me understand what has happened despite two years of peace and stability.

I can only speculate that the move to a larger system which has more hiding places has triggered some sort of territorial response?

From my experience, the more open space there is, the more aggression you will see. I'm not sure if ATF's are territorial or not but it has been proven that if a tank is overcrowded, they tend to not pick on eachother as much because when they chase after 1 fish, 3 more come in so they just kinda get over it, but when there's more space, they tend to be more aggressive and their true personalities start to show. This has been proven with multiple species.
