porcupine puffer ate my firefish

i have a baby porcupine puffer fish about 2 inches.. my purple fire fish passed away and he decided to eat the fish before i could remove it from the tank. he also decided to take out a green watchmen goby which the petstore advised me he wouldn't bother.. are either of these toxic? he spit up the remains of the fish but now refuses to eat any food and just lays at the bottom of the tank. as before he would swim around and was very active.

 

first off, just out of curiousty what size is your tank? how old is it?

 

I don't think they are toxic, your puffer is probably just to full to move. when they get full they have a habit of spiting stuff back out.

 

Probably some indigestion or just full, that's quite a meal. Puffers are aggresive and will eat other fish but those fish aren't toxic to it so there shouldn't be a problem.

 

it's a 75 gallon tank.. been up for several months..

 

just out of precaution pay close attention to your ammonia nitrite nitrate levels. what kind of filtration do you have? how many lbs of live rock? that is if its a fowlr.

 

i have a fluval 405 on it and a protein skimmer. i have live sand in the tank. haven't added any live rock to it yet. the levels have been fine.

 

i don't have a lot of fish in the tank, the fish i do have are all fine. the puffer ate the other two monday evening, and since then has just been kinda laying around. suddenly last night he turned away from eating food and today he's just laying around.

 

i would check your parameters now after the fish have died and remains have had a chance to break down. if your tank is not well established and you dont have LR containing beneficial bacteria to break down the uneaten remains, there is a chance you could have a spike.

post your parameters after you check them, we are here to help.

also it wouldnt hurt to do a water change.

 

how much live rock would you recomend? i have a lot of plants and chunks of coral that i bought at the pet shop. isn't the live sand's bacteria beneficial aswell?
