hi i have a 3" red devil in a 5 gallon tank and I have a 6" JD, 4" green terror, a female convict about 3", and a 7" pleco inn a 37 gallon tank. i'm getting either a 75 or 90 gallon tank in a few days. i'm just wondering if they will still reach full size they are all less than 10 months old and i got the red devil about a month ago. my convict doesnt seem to grow anymore at all its pretty small is that normal? i just dont want to stunt their growth

The red devil won't survive in a 5 gallon tank.
Assuming that its a common pleco, I think the bio load will soon become too much for that 37 gallon tank (or it already has). You need to upgrade the tank soon. At the sizes you currently have, you should be worrying about your fish dying due to excessive ammonia, not stunting.
 
ya, i agree. upgrade or sell because that is cruel to the fish. If i was you, i would sell the red devil because you won't be able to house it with what you already have in that 75g. Don't worry about stunting (its going to happen with what you have) because your fish are going to die of excessive ammonia.
 
Sounds like the jd and gt are already stunted if thats all they have grown in 10 months. Also, sell the red devil.
 
3" is about tops for a female convict, so don't expect that much more growth out of them.

I've seen seemingly stunted fish continue to grow when given an appropriate sized aquarium. Some don't though.

The red devil will wreak havoc in your tank, so agree that you should trade for something else or sell it.
 
the jack dempsey is like 6 months and the green terror is about 4 months and the pleco is around 7-8 i forget, should they be bigger? i have 2 aquaclear 50's on the 37 gallon with purigen in them and i change like half the water every week, as for the red devil ill see if he will get along but i doubt it ill just stick him in the 37 gallon for the time being when i move the others in a week or two
 
Stunting is caused by high nitrates not tank size. Those fish in the tanks you've got them in though....that's cruel. A 90 isn't even big enough for those fish. It's psychologically cruel to even start a RD out in a 5 g! That's a bucket. The fish lives in a bucket.
 
pattycr125, thank you for coming here for help. Those fish are not going to live long or quality-filled lives after what you've done to them. You'll want euthanize these tortured souls, then get a 200gal tank which will better suit your tastes, or several 90 gal for wet pet setups (one large fish per tank). The fish you like do not always get along, so it will certainly be a safer practice to keep each fish in its own tank. Large tank.

While nitrate levels will contribute to fish stunting, saying tank size doesn't have anything to do with it is incorrect.

In example, a friend gave me some marbled ctenopoma and an unnamed species of leporinus. Mine were kept initially in a 65 gallon tank and then in my 210. I do far more water changes and tank maintenance than he does. His in his 2600 gallon tank grew to 3x the size of mine. I returned mine to him and they grew to match the ones he had.

So, his higher nitrate larger tank grew larger fish than my lower nitrate smaller tank.

Your information is incorrect.

No, my information is NOT incorrect, thank you very much. Don't tell me you haven't read the studies on this?? (Although I agree that a 5 g tank will physically stunt a fish.) But you can raise an Oscar (for cruel instance) in a 30 g tank and do enough water changes to keep nitrates around 5 ppm and that Oscar will grow to it's predetermined size.
