Looking To Add Compatible Fish To 75 Gallon

HI All!

I just joined this forum a couple days ago and this is my first 75 gallon aquarium (I've had smaller aquariums). I am in the midst of transferring fish from a 55 gallon tank at work to my 75 gallon tank at home. I will have the new aquarium properly cycled (transferring some bio balls from a current tank at work and putting into my new tank to accelerate the bacteria growth) with a 300 watt heater, Fluvaal filter (250 gallon capacity and 700gal/hr cycle), will also take some water from the tank at work and cycle about a week prior to the fish transfer. If there is anything I am not thinking of or forgot to mention, please let me know! I will also do a water test the day before I transfer the fish.

I will be transferring:
(3) Peppered Cory cats
(6) Black Harlequin Rasboras
(5) Rosy/Candy Can Tetras (aquarium sent both instead of all Candy Cane)
(2) Longfin Congo Tetras
(4) Cherry Barbs
(2) Bushynose Plecos

All fish fully grown will have 49ish total inches and I will have ~26 inches left until I reach 75 (I heard it should be 1inch of fish/gallon, is this right?). Do you guys/gals have any advice on which other fish I should/could add? Any species of freshwater that is medium/non-agressive that you personally like or think would be a great fit for additions (BTW, I have a natural medium color gravel with dark aspects intermittent throughout along with some bland green fake plants and some bright blue/purple plants with the fake (also colorful) coral reef structures.

This was long winded and I will add pictures for a better idea if reqested. Thank you for reading and commenting!!!

Get 3 more peppered Cory's and 3 more Congo tetras there schooling fish and 75 is way more than enough space to add some fish the ....don't follow the 1in per gallon rule ....It doesn't always help ...I wish ik some other people who can help u out about the 1inch rule.cory needs soft substrate like sand so they can sift in it for food...plus it's easy on their barbels.....Black sand will probably look nice..Oh yea add some pics

If your adding all at once your going to have a huge ammonia the nitrite. Moving water from another tank will do nothing, the bacteria grows on surfaces. Using some bioballs to start a cycles will be cycles enough ammonia for a couple of fish, not 20. If your set on doing it all at once, using the old filter with old media in it, and transfer all the gravel from the old tank. If you don't want them to mix with the new stuff you can put it in a stocking and hang it in the tanks for a few weeks.

For new fish
One option: The tetras can be stunning in schools of over 10
Corys will be a lot happier in group of 5-6
If you llike he tetras, you can grab a school of a differently colored species like Black Phantom, Serpae, or Lemon Tetra


I personally love goruami and think your tank doesn't have much top level swimmers. Blue gourami and their varients (gold,three spot, etc) are too aggressive.
But Pearl Gouramis are great if you do just one male and a few females, Thick-lipped gourami are an even better choice, they're neither shy nor aggressive. Honey gouramis are also good, they arre shy and will hide but you can get a lot more of them.

 

Awesome, thanks Wickette! I didn't even think of that, great advice.

This is unwanted advice but I always do this when upgrading a tank, have never lost a fish and never got an ammonia spike.


For about $10 you can buy a powerhead, and use a plastic water/soda bottle to make a very efficient- bio-filter. For a 55-75g tank, I recommend you use a 1 gallon water bottle, the 2.5 gallon bottles are ideal but probably too much hassle,.

-Use scissors to make a hole the size of the pump's nozzle about 3" from the bottom of the bottle (doesn't need to be perfect).
-Push the in-take nozzle of the pump into the hole.
-Cut the top of the container so its bigger than your fist.
-Fill the bottle with old tank gravel/old fitter media
-Place bottle in a corner of the new tank, so the pump is pressed between the glass and bottle (pump will stay in place and the flow won't bother the fish)
DONE!
-just don't remove it all once, remove a little bit every few days until its empty.


This filter is great to keep around as backup too. I run mine with some media from my primary filter when I go on vacation in case my canister filter dies while I'm away. AND if there is a black out, most of the bacteria in a canister filer will die in 1 or 2 days, it will take weeks for the bacteria in a submerged filter to die.

the other way to do it is use a submersible pump, put it in the bottom of the container, run a tube out of the container, advantage of this is you done need to make a hole in the bottom. Disadvantage: you need to buy tubing, and secure the tube so it doesn't spit water out of the tank, and make some sort of netting to keep gravel from getting into the intake.

Black phantoms are so amazing I have a school of 5 .....1 male 4 females......he can also try apistogramma cacatouides

First is the new tank and second is the existing tank from work I am transferring from
