Betta Fish Tank Plants Complete Guide: Species List

Plants sold as “betta plants” at a big-box pet chain are often houseplants rotting in water, not true aquatics. Peace lilies and lucky bamboo top that list, and neither survives fully submerged. This betta fish tank plants complete guide from Gensou Aquascaping at 5 Everton Park runs through twelve genuine aquatic species that tolerate low light, 26-28°C tropical temperatures, and the calm water bettas demand. Each entry notes care level, placement zone, and typical SGD pricing at Singapore shops.

What Makes a Plant Betta-Friendly

The shortlist reads the same in every serious hobbyist forum — slow-growing, tolerant of low light and low-tech (no pressurised CO2), safe leaf texture for delicate fins, and undemanding on fertilisation. Bettas do not eat plants, but they rest on broad leaves near the surface, so species like Amazon sword and Anubias nana earn their place twice over. Grab a well-stocked selection at live plants.

Anubias Nana and Anubias Petite

Rock-mounted epiphyte, 5-10 cm, dark green wide leaves. The gold standard betta plant — nearly indestructible, glows under low light, and tolerates the full 24-32°C range of a poorly-temperature-controlled Singapore HDB tank. Anubias petite (nana variant) suits nano 19-litre builds; full-size nana works in 40-litre and up. SGD 8-15 per portion at Polyart and Nature Pet.

Java Fern Varieties

Microsorum pteropus — narrow-leaf, Windelov, Trident and Philippine. All epiphytes, all glued to driftwood or rock. Expect the starter pot to look battered out of the bag; within 4-6 weeks new submersed leaves replace the emersed ones. Java fern prefers slightly cooler 22-28°C, so it tolerates Singapore conditions well but struggles past 30°C. SGD 10-18 per pot; Philippine variant commands a SGD 3-5 premium.

Java Moss and Christmas Moss

Classic background carpet plants. Tie fragments to stones or driftwood with black cotton thread; the thread dissolves as the moss roots itself. Christmas moss grows more geometric “branches” than java moss’s stringy mat, but both accept any flow condition and low light. Moss also doubles as shrimp grazing ground if you add cherry shrimp later. SGD 5-10 per golf-ball portion at Qian Hu.

Cryptocoryne Wendtii

The mid-ground workhorse in green, brown and tropica variants. Root-feeder — plant rhizomes in aqua soil and expect a full-leaf melt in week 2 as emersed growth dies back. New submersed leaves emerge from the crown within 3-4 weeks. Mature wendtii throws 15-20 cm leaves and covers substrate gaps effectively. Pair with root tabs every 3 months for steady growth.

Amazon Sword

Echinodorus bleheri — the classic sword as focal plant for a planted betta tank. Reaches 30-40 cm tall, wants aqua soil plus monthly root tabs. Old emersed leaves yellow and fall; do not panic, trim them at the crown and let new submersed growth fill in. One adult sword dominates the back of a 40-60 litre tank. SGD 12-20 per specimen at C328 Clementi.

Cryptocoryne Lucens and Parva

Smaller crypts for foreground and mid-ground placement. Lucens stays 8-12 cm, parva is the true carpet crypt at 4-6 cm. Both prefer stable parameters; moving them around the tank resets the melt cycle each time. Plant once, leave alone, dose ferts. Parva is genuinely slow — expect 6 months to establish a small carpet in a low-tech 19-litre.

Bacopa and Ludwigia for Stem Plants

If you want vertical green in the back, Bacopa caroliniana and Ludwigia repens tolerate low-medium light and betta temperatures. Cut tops, replant cuttings for thicker bushes. Stem plants need more light than rhizome species, so pair with a Chihiros or Week Aqua nano LED. Ludwigia develops reddish tones under stronger light — a nice contrast to the green rhizome plants up front.

Floating Plants

Red root floaters, salvinia minima, and dwarf water lettuce shade the surface and consume excess nitrate aggressively. Bettas love them — the root system mimics the floating mats they build bubble nests in. Thin out weekly to prevent full surface coverage blocking gas exchange. One caveat — floating plants impede feeding if they form a complete mat. Keep 30-40% open surface water.

Plants to Avoid

Peace lily, lucky bamboo, pothos (submerged), aluminium plant, any “betta plant” pod sold in closed plastic cups at supermarkets. None of these are true aquatics and they rot within weeks, fouling water and triggering ammonia spikes. Dwarf hairgrass and carpeting plants (Monte Carlo, HC Cuba) are genuine aquatics but demand high light and CO2 — wrong fit for a low-tech betta tank.

Fertilisation and Maintenance

Weekly liquid dose of JBL NanoBiotopol Betta at 1 ml per 10 litres covers nitrogen, potassium and trace elements without burning betta gills. Water changes at 25% weekly export excess. Trim yellowing leaves at the base with scissors. Substrate-vac only in open areas, not around planted roots. A mature planted betta tank stabilises around month 3.
