coexisting aggressive fish

Wow, you got a crazy mix going on there, man! Since everyone else covered all of the possible compatibility issues already, I'll just say this...try to target feed the puffers with frozen food 2-3 times a week if you can. I've had many customers come in with dead puffers to return and I hear a common thread through all of their stories, that is they were told by someone I work with that puffers will eat flake food. Now maybe some species will, I guess, but I've never seen any of ours eat flakes EVER and when this person tries to give them flakes on one day and I come in the next and give them frozen bloodworms they are ravenously hungry and attack the food. The worst part is that certain someone giving some bad advice out is my boss. :mad:
 
****...thats alot of diffrent kind of fishes in one tank thats not even in the 100+ gals

And yeah, they may be peaceful since there first introdouced to the tank and are scared and shy, but once they get used to it its gonna be world war 3 in your fishtank...
 
I did a lot of research and talking around before I bought it. I was not told to feed the puffer flake food, no, he is on bloodworms as I type this. But, what I was told was, as they mature they get to be picky eaters and I might attempt to vary their diet some, and they might take to flake food if they tired of bloodworms. I feed the puffer seperately, and do feed it bloodworms. I've read cases of rather relaxed puffers that only deal out minor nipping in community tanks if surrounded with bigger fish in the beginning. I have every intention for watching out for it, as well as the safety of the others (and I won't be getting rid of him if he's a 'problem', I will raise him seperately.) As stated before, I found him rather tattered, and he's a really little guy as of right now, no bigger than the fiddler crab.

The puffer will not survive on bloodworms--they must have crunchy food in their diet to wear the beak trim, without this it will overgrow and prevent the puffer from eating. You need to get a better ID--BW puffers do not survive for long in FW tanks, and tend to have many skin diseases when kept in FW for long.

Basically, you have a disaster in waiting. The tank is overstocked, the fish are not compatible. At a guess, the only reason you havent' seen some serious agression is that everyone is so stressed they don't know what to do. Good luck--the fish will need it more than you.
 
Do you know what kind of shark you have? Also what size is your other tank? You might want to consider moving some of the fish you have into the other tank ASAP. I'm not sure why you want to wait until something goes bad to fix the situation you have. The fish are way overcrowded and stunted growth is not really something you "see" until the fish are so damaged that they begin dying and showing signs of disease on a regular basis.
 
It's a bala shark, I'm pretty sure. I didn't grow it, my neighbors were moving and just gave it to me, so he's fully grown. I'd like to get rid of the kissing fish but I don't know anyone would take them. I've been told by the one from who I purchased the puffer as well as multiple sites offering info on them have said that puffers can survive in anything from fresh to marine water. Is this really not true? Everything and everyone else is wrong and the few here are right? The other tank is a 7 gallon, I considered putting the puffer in that if he needs brackish and solitary conditions.
 
Check with the local stores around you and see if they will take any of the fish, most of the big chains won't but alot of the smaller stores will.
 
No, it's not true. Yes, each type of water does have puffers, but they tend not to thrive when kept in the wrong water type. FW puffers will not survive BW for long, nor SW at all. BW puffers can survive short term exposure to FW, but ultimately need BW to survive--or migrate to full marine conditions. There are a lot of people who wil consider themselves successful with puffers who have had them for less than 6 months. I'd listen to the people who've kept them alive for the full, normal lifespan--10+ years, in many cases.

A 7 gallon tank is not large enough for any but the dwarf puffers.
