75 Gallon Community Tank | Stocking Ideas

Main summary

Key takeaways

Lifestyle

75-gallon community tank overview (≈280L)

  • The tank is 75 gallons (≈280L) with ~30–35 fish.
  • Overall vibe: a semi-aggressive community tank—most fish are semi-aggressive, with a couple of exceptions.

Main show fish & feeding/plant behavior

Electric Blue Acaras (2 total)

  • One male + one female; hoping they may pair/mate (not yet).
  • Temperament: mostly peaceful for cichlids, but territorial with each other.
  • Size: about 4–6 inches (nearly full grown).
  • Tank habits:
    • Dig in the sand
    • Tug at plants, especially stem plants (back plants get pulled up often)
    • Hearty-root plants like Amazon swords and Java fern usually stay intact
  • Diet: eats almost anything (not picky)
  • Cost anecdote:
    • Bought small (~1.5 inches) for about $20
    • Larger juveniles may cost about double

Blood Parrot Cichlid

  • Still a juvenile; expects ~6–8 inches.
  • Temperament: likely more aggressive than the electric blue acara, but described as overall peaceful.
  • Behavior:
    • Intelligent/odd behavior: swims sideways and upside down to inspect things
    • Digs through dirt
    • During feeding: gobbles everything and steals food from other fish
  • Compatibility guidance: keep with fish that are fast, semi-aggressive, or tough enough to get their own food.

Other cichlids

Peacock Cichlids (2 total)

  • One yellow and one dark gray
  • Size: 4–6 inches
  • Temperament: more aggressive, though aggression is mostly between themselves.
  • Interesting note (after a rescaping):
    • After a rescape (removing/rearranging), the dominance switched
    • The dark gray was dominant before; after rescaping, the yellow became dominant
  • They also dig/pull at the substrate like other sand-working fish.

Schooling barbs (fin nippers, best kept in numbers)

Tiger Barbs + Green Barbs + “Bino” Tiger Barb

  • Total barbs: about 15 (between tiger and green)
  • Reputation: semi-aggressive and can be fin nippers
  • Key tip: a large group reduces sustained aggression
  • They school together (including tiger and green barbs mixed)
  • Behavior pattern: about once a month the tank becomes a “war zone” for ~5 minutes, then they calm down and return to grouping/digging
  • Recommendation: get a larger group (speaker suggests 10-ish)
    • With only 2–4, one individual may get targeted harder, increasing risk of injury/death
  • Feeding: even with food-stealing tendencies, the barbs still get their share

Midwater/upper tank fish

Serpa Tetras (~7)

  • Temperament: community/pacific, but confident rather than skittish
  • Why this matters: in semi-aggressive tanks, smaller fish must not flee excessively
    • Fish that dart/run away can attract more chasing/picking
  • Contrast mentioned: rummy nose tetras would be more skittish, likely leading to them being picked on and not lasting as long

Livebearers / algae control

Platies (multiple generations)

  • Total inside main tank: about 5
  • Most platies are kept in an outdoor water planter/mini-pond:
    • ~15–20 living outside for about a year
  • Plan for the next season: redo the outdoor planter/pond
    • Viewer can comment if they want a rebuild
  • Notes:
    • Females can reach ~2–3 inches
    • Temperament: peaceful but hardy and they hold their own
    • Habitat: mostly upper/top layer of the tank
  • Benefits:
    • Breed like crazy
    • Excellent algae/diatom eaters
    • They do algae even better than expected (including compared with algae-specialist fish like some plecos/autos mentioned)
  • Diet observation: can be seen picking algae off leaves, glass, and driftwood

Cleanup crew / bottom maintenance

Corydoras catfish school

  • About 7 total (including Venezuelan corys and peppered/other corys)
  • Job:
    • Maintain the bottom by collecting what others miss
    • Their movement stirs/lifts debris toward the filter
    • Helps keep the sand cleaner/whiter
  • Breeding note: cory eggs often don’t hatch into fry because the eggs are typically eaten

Spotted Raphael catfish (night-active)

  • Only comes out at night; appears black with white spots with an armored look
  • Size: small—currently near adult size for the speaker; expected to stay relatively small
  • Behavior:
    • Ribbons/ram-like swimming into obstacles
    • Eats anything not eaten at night
  • Feeding approach: uses sinking pellets so nocturnal catfish and corys can actually eat

Key “system” takeaway

  • Fish are chosen so each zone has coverage:
    • Upper/mid fish handle active feeding and grazing behaviors
    • Platies and barbs/tank residents help reduce algae
    • Corys + catfish handle bottom leftovers and debris
  • Cleanup crew roles are described as essential to keep tank layers clean.
