Here are some interesting info from some owners & other sites:
"I recently obtained one of these fellas for 20 bucks at my local LFS.
To say the least this fish is on crack! He was all settled in my Freshwater tank , with a nice sandy bottom with some live plants and rocks. I also kept 2 kissing gouramis an electric blue one glass cat and 4 red eye tetras.
Well before bed last night I watch my fish everynight before I go to bed,but anyways he starts going up and down the Tank Splashing Horrifically at the top. Well he ends up settling down finally so I go to bed , mind you my water is fine and nothing is wrong with the tank.
Well Next morning wake up and wammo , theres my lil guy laying in the sand having a good ol time while my tank was hit by a major earthquake
Total Casualties:
4 Red Eye Tetras
1 Kissing Gourami ( This fish was 3 inches long)
1 Electric Blue.
All plants uprotted and destroyed
Plastic Scenery moved 4 inches.
He seriously had some problem that he couldn't cope with I have read the available info on the and I highly suggest this fish to live in a Single Tank.
But they are very pretty and Cool fish , But Community isn't in there Vocab."
Here's some more info: "Arrowhead, T. suvattii (valid): No noticeable external differences between the genders. Designed to eat fish. Not recommended in a tank with fish you value. Occurs only in the Mekong basin of Thailand and Laos, in the mainstream and larger tributaries in places with muddy or rocky (as opposed to sandy) substrate, but not in the rapids like some of the other Mekong basin puffers. It resembles the T. miurus of African origin, but the resemblance has not yet been tested for a hypothesis of relationship."
"A exclusively freshwater fish from South Asia, is not at all meant to be together with groups of fish in an aquarium."
"T. suvatti pursue their prey in addition, quite speedily. They are nearly always successful and their attack is optimized by their strong teeth. Small fish are devoured immediately under violent chewing movements in the whole. Larger prey fish are first killed and gradually eaten.
Aggression is not as strongly pronounced with this kind, in my observations, as with the Congo Puffer. Preferable however is a large aquarium with as large, well structured a surface area as possible. There the fish can stay out of the puffer's way. Later assigned animals are usually mercilessly pursued by the puffer already acclimatized. Often an uncommon attitude does not permit the keeping of these fish with other species or even their own kind. If kept with others they should be frequently observed.
To intruders T. suvattii react immediately with great unrest. To begin they will only stare at the intruder. If the puffer is over the opponent in the clear, he ascends with threateningly lowered head, opens the muzzle and swims slowly towards the intruder. Usually this is sufficient to inspire the enemy to leave. If that is not the case, T. suvattii shows the opponent its broadside and inflates its body through water sips to a imposing size. Inflating makes unpleasant noises. Probably the opponent is to be irritated and intimidated by these unusual noises. Threateningly and impressively the inflated puffer swims in a zigzag before the opponent back and forth. The head is lowered and the open muzzle with the sharp teeth displayed. If the intruder does not vacate at this point the puffer will inflict serious bites.One can simulate this interesting behavior with the help of a small hand mirror. The puffers will attack their own mirror image."
